Description

Drum type washing machine

Technical Field

The present invention relates to a washing machine, and more particularly, to a drum type washing machine.

Background

When the drum type washing machine is in operation, the inner drum rotates at high speed to cause the washing to generate local overlarge centrifugal force to cause vibration, and the vibration caused by the inner drum is transmitted to the outside of the drum type washing machine through the outer drum and the machine shell, therefore, the drum type washing machine with the existing structure needs to leave a gap between the inner drum and the outer drum and a gap between the outer drum and the machine shell, in order to prevent the vibration from being transmitted from the inner drum to the machine shell through the outer drum, a spring and a damper are inevitably arranged between the outer drum and the machine shell to buffer and damp the vibration of the outer drum, so that the washing machine is ensured to have enough space to generate shaking displacement during high-speed rotation movement.

Under the condition of standard casing width (600 mm), the diameter of the inner cylinder of the mainstream drum washing machine (such as the capacity of 10 kg) on the market at present is about 500mm mostly. However, the existing drum washing machine also has two common problems: firstly, a damping system composed of springs and a shock absorber is generally two supporting dampers at the bottom and two springs at the top, the damping system composed of four components is in the same plane and is often in the central plane of the inner cylinder in the front-back direction, when the mass center is randomly deviated, the deviation in the front-back direction is often generated, and the damping system can not play the best effect; second, most drum type washing machines are not separately installed but are compliant with the existing installation environment (e.g., in a built-in environment), which requires that the size of the drum type washing machine be limited by the size of the space of the actual installation environment, which causes many difficulties in attempting to enlarge the diameter of the washing tub in the structure of the drum type washing machine.

In order to solve the above problems, a washing machine in which an outer cylinder is fixed and a damper buffer assembly is disposed between the inner cylinder and a cabinet is disclosed in patent No. ZL201080017293.4 entitled "washing machine". The cushion assembly of this patent is secured in a suspension configuration to a bearing housing that is supported on a housing base by the suspension assembly and includes a laterally symmetrical attachment structure that extends forwardly and then attaches to the bottom of the housing.

The inner cylinder in the patent is fixed on a chassis bottom plate by an L-shaped cantilever beam, and only the lower part of a roller is provided with constraint buffering, so that when the eccentric direction is above the roller during high-speed rotation, better constraint buffering cannot be provided; in addition, the inner tube of the above patent has no counterweight to connect, the quality is lighter, therefore under the condition of smaller eccentric mass, the mass ratio relative to the whole rotating object is very large, the deviation is obvious, because the displacement of the vibration of the inner tube can not be avoided, a gap of about 25mm is still left between the inner tube and the outer tube, the diameter of the inner tube can only be about 520mm, and the lifting is not obvious compared with the diameter of the inner tube of the existing mainstream product drum washing machine.

In summary, in order to solve the problem of effectively reducing the vibration of the rolling washing machine in the washing process and increase the diameter of the inner cylinder as much as possible, further improvement and perfection are to be made on the existing rolling washing machine.
