preferably, the waterproof member 100 includes a waterproof ring 101, and an end surface of the waterproof ring 101 near one side of the casing 32 is provided with a waterproof edge 102 folded outwards, and the waterproof edge 102 is inclined from the hanger bar 10 to the casing 32 in a radial direction.
In the above-mentioned solution, since the plurality of components generating the damping force of the present invention generate the damping force by friction with the sleeve 32 fitted outside the suspension rod 10, instead of directly contacting and rubbing with the suspension rod 10, in order to prevent water from entering between the sleeve 32 and the suspension rod 10 or water from entering into the accommodating chamber 41 of the upper spring seat 40, thereby generating abnormal noise or causing the damping force to fail, the waterproof member 100 is provided at the upper end of the sleeve 32 for preventing water from entering into the sleeve 32 and/or the accommodating chamber 41.
In detail, waterproof 100 includes waterproof ring 101, and waterproof ring 101 cover is established on jib 10, and between jib 10 zonulae occludens, waterproof ring 101 is close to a side end face of sleeve 32 is equipped with the waterproof edge 102 of turning over outwards, waterproof edge 102 certainly jib 10 is along radial to sleeve 32 direction slope presents the umbrella structure, and waterproof edge 102's outer fringe should cover sleeve 32's upper end at least, is favorable to water along waterproof 102 landing of following, avoids the water to get into sleeve 32 and/or hold chamber 41.
In order to increase the service life of the flashing 100, the flashing 100 is made of a flashing material, preferably the flashing 100 is made of a stainless steel material.
The hanger bar assembly of the present invention further comprises a hanger bar base 110 fixedly installed at an upper end of the hanger bar 10, and the hanger bar base 110 is hung at an upper portion of a cabinet of the washing machine. A gasket is additionally arranged between the hanging rod seat 110 and the box body of the washing machine, so that the damping effect is increased.
The invention also provides a washing machine with the suspender assembly. The washing machine with the hanger rod assembly can keep quiet and stable dehydration starting and running, realize quiet washing, reduce the cost of the washing machine to the maximum extent and improve the quality performance of the washing machine.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
