Title:
WASHING MACHINE DAMPING STRUCTURE, DESIGN METHOD, TRANSVERSE SHOCK-ABSORBING APPARATUS, AND WASHING MACHINE
Document Type and Number:
WIPO Patent Application WO/2019/019553
Kind Code:
A1
Abstract:
A washing machine damping structure, a design method, a transverse shock-absorbing apparatus, and a washing machine. The damping structure (50) comprises a guiding sleeve (3), and a guiding rod (1) having one extremity extended into the guiding sleeve (3). Provided on the inner side of the guiding sleeve (3) is a damping piece (2) for generating in tandem with the guiding rod (1) a damping force. The guiding rod (1) is provided at the middle with a no-load section (12) and working sections (11) located at either extremity of the no-load section (12). The diameter of the no-load section (12) is less than the inner diameter of the damping piece (2); the diameter of the working sections (11) is greater than the inner diameter of the damping piece (2). By means of providing the no-load section (12) and the working sections (11), the provision of a variable damping force is implemented, when an outer drum (20) is experiencing a large vibration, the damping structure (50) provides a sufficient damping force to prevent the outer drum (20) from hitting a housing; moreover, within a safe vibration amplitude for steady operation of the washing machine outer drum (20), the damping structure (50) provides a reduced damping force or provides no damping force, thus not only avoiding the problem of hitting the housing when the washing machine is spin-drying at a low speed, but also ensuring that, when spin-drying at a high speed, overall unit noise does not increase due to increased vibrations being transmitted to the housing (10).
