AI Technical Summary
While existing home appliance moving mechanisms aim to avoid vibration and noise, the roller assembly cannot return to its proper position, thus affecting the moving function.
The base is designed with a downward-expanding vent, within which the roller assembly's shaft rises or falls. Combined with an inclined wall and a reset component, this ensures that the roller experiences minimal friction before making tight contact during its ascent, achieving smooth repositioning.
This ensures smooth operation of the roller assembly during lifting and stability during use, avoids vibration and noise, and guarantees the normal function of the moving mechanism.

Abstract
Claims
1. A moving mechanism for a domestic appliance, characterized in that, include: The base has a base body (110) and a first vertical wall (120) provided at the bottom of the base body (110). The first vertical wall (120) is provided with a receiving opening (121), which is configured as a downwardly widening flare. The roller assembly (130) includes an adjusting member (131) and a roller (132). The adjusting member (131) is disposed on the base and can drive the rotating shaft (133) on the roller (132) to move upward and be placed in the receiving opening (121) so that the roller (132) rises and retracts and contacts the first vertical wall (120). The adjusting member (131) can also drive the rotating shaft (133) to move downward so that the roller (132) descends to support the household appliance.
2. The moving mechanism for household appliances according to claim 1, characterized in that, The first sidewall (1211) of the receiving port (121) is configured as an inclined wall.
3. The moving mechanism for household appliances according to claim 1 or 2, characterized in that, The adjusting member (131) is configured as a connecting arm, one end of which is rotatably connected to the base, and the other end is rotatably connected to the roller (132) via the rotating shaft (133). The moving mechanism also includes a moving bracket (140), which is movably disposed relative to the base body (110). The moving bracket (140) has a pushing structure (1421), which is used to push the roller assembly (130) when the moving bracket (140) moves in a first direction, so that the connecting arm rotates to the position where the roller (132) is lowered. When the moving bracket (140) moves in a second direction opposite to the first direction, the connecting arm is allowed to rotate back to the position where the roller (132) is raised and retracted.
4. The moving mechanism for household appliances according to claim 3, characterized in that, The first upright wall (120) is provided with at least two of the receiving openings (121) at intervals in the moving direction of the movable support (140); The number of roller assemblies (130) is at least two sets, and the rotating shaft (133) of each roller assembly (130) is correspondingly provided in each of the receiving ports (121). The number of pushing structures (1421) is at least two, which are used to push each roller assembly (130) correspondingly. The first sidewall (1211) of one of the receiving ports (121) and the second sidewall of at least one of the remaining receiving ports (121) are respectively formed as inclined walls with opposite inclination directions.
5. The moving mechanism for household appliances according to claim 2, characterized in that, The receiving port (121) has a second sidewall (1212) opposite to the first sidewall (1211), and the second sidewall (1212) is arranged vertically or inclined.
6. The moving mechanism for household appliances according to claim 1, characterized in that, The base body (110) has first vertical walls (120) on both sides. The rotating shaft (133) is located in the receiving opening (121) of the first vertical walls (120) on both sides. The rotating shaft (133) has rollers (132) at both ends. The rollers (132) on both sides are located outside the first vertical walls (120) on both sides.
7. The moving mechanism for household appliances according to claim 1, characterized in that, The receiving opening (121) extends through the vertical edge of the first upright wall (120).
8. The moving mechanism for household appliances according to claim 3, characterized in that, The moving mechanism further includes a reset member (150), which is used to drive the connecting arm to rotate back to the position where the roller (132) rises and retracts after the moving bracket (140) moves along the second direction.
9. The moving mechanism for household appliances according to claim 8, characterized in that, The connecting arm is rotatably connected to the base via a connecting shaft (134). The reset member (150) is a single torsion spring or a double torsion spring. The single torsion spring or the double torsion spring is sleeved on the connecting shaft (134) and abuts against the movable bracket (140).
10. The moving mechanism for household appliances according to claim 3, characterized in that, The moving mechanism further includes a handle (160), which has a first connecting part (161) and a second connecting part (162). The first connecting part (161) is hinged to the base body (110), and the second connecting part (162) is driven to the moving bracket (140) to drive the moving bracket (140) to selectively move along the first direction or the second direction.
11. The moving mechanism for household appliances according to claim 1, characterized in that, The base also includes a first mounting plate (171) and a second mounting plate (172) disposed on opposite sides of the base body (110) along its length.
