The positioning sleeve 41 is arranged on the outer wall of the lower box body 22, and the lower end of the positioning sleeve 41 is a blind end, and the upper end has an opening. The upper end of the movable rod 42 is constrained on the outer wall of the upper box body 21, and the lower end can be inserted into the positioning sleeve 41 so as to move up and down. The limiting assembly 43 is arranged between the positioning sleeve 41 and the movable rod 42 and is used to locate the relative positions of the two. With such a structure, it is convenient to realize the up and down movement of the upper box body 21 relative to the lower box body 22, thereby realizing the adjustment of the overall height of the box body.

[0036] Specifically, a plurality of positioning holes 411 arranged at intervals in the upper and lower sides are provided on the side wall of the positioning sleeve 41, and correspondingly, a transversely arranged mounting hole 421 is provided on the side wall of the movable rod 42, and a first elastic member 431 (set as a spring in this embodiment) and a stop pin 432 are sequentially arranged in the mounting hole 421 from the inside to the outside, and the first elastic member 431 keeps the stop pin 432 inserted into the positioning hole 411 at all times, and the positioning hole 411, the mounting hole 421, the first elastic member 431 and the stop pin 432 together constitute a stop assembly 43. The above structure is adopted to facilitate the up and down driving of the upper box body 21, and to timely stop its height after each displacement, thereby improving the operational reliability.

[0037] In this embodiment, an adjustment mechanism 5 is provided at the lower edge of the base 1, which can fine-tune the height at various locations so that the washing machine can be automatically leveled. Since the telescopic structure 3 of this embodiment is a flexible connection structure, if the entire dishwasher is not in a horizontal state, it is easy to cause the dishwasher to cause strain or even tearing of the soft connection part (telescopic structure) during the adjustment process, resulting in the dishwasher being unable to be used normally. In order to solve this problem, the utility model is provided with the above-mentioned automatic leveling adjustment mechanism 5.

[0038] The adjusting mechanisms 5 are at least four groups and are respectively arranged at the four corners of the base 1. The four corners of the base 1 extend outwards to form mounting seats 11 for mounting the adjusting mechanisms 5. The above structure is adopted to improve the reliability of leveling.

[0039] The adjustment mechanism 5 of this embodiment includes a driving member 51, a pressure sensor 52 and a second elastic member 53. The driving member 51 is a motor, which is arranged at the top of the mounting seat 11 and arranged with the output shaft 511 facing the driving member 51. The mounting seat 11 is provided with an axial hole 111 for the output shaft 511 of the driving member 51 to extend downward. The pressure sensor 52 is sleeved on the outer periphery of the driving member output shaft 511 through a threaded structure and can move up and down. The second elastic member 53 is a spring, which is arranged under the pressure sensor 52 and the lower end of which extends out of the axial hole 111. The outer periphery of the output shaft 511 of the driving member 51 is formed with an external thread, and the outer periphery of the output shaft 511 is sleeved on the nut 512. The pressure sensor 52 is formed into a ring shape and sleeved on the outer periphery of the output shaft 511, pressing between the lower surface of the nut 512 and the upper end of the second elastic member 53. During the leveling operation, the driving members 51 of the adjusting mechanisms 5 at the four corners of the base 11 will operate simultaneously. Since the nut 512 is threadedly connected to the output shaft 511 of the driving member, the nut 512 will carry the pressure sensor 52 and the second elastic member 53 to operate downward, causing the compression amount of the second elastic member 53 to gradually change. Since the pressure sensor 52 is fixed to the upper end of the second elastic member 53, the pressure sensor 52 will feel the pressure during the compression of the second elastic member 53. When the pressure on the pressure sensor 52 reaches the set value, the driving member 51 stops running, and the four corners of the washing machine have been adjusted to the desired state. The pressure values ​​of the adjusting mechanisms 5 at the four corners of the base 11 are set to equal values. When each corner stops running, the pressure on the second elastic members 53 at the four corners is the same, and the dishwasher is in a horizontal state.

[0040] The cleaning machine of this embodiment can automatically adjust the height according to the size of the cabinet to ensure compact installation, reduce vibration amplitude and noise, meet the user's installation requirements of cabinets of different heights, and provide more convenience for users.
