Below with reference to the accompanying drawings the suspension dampening assembly for washing machine according to the embodiment of the present invention is described in detail.
As depicted in figs. 1 and 2, according to the suspension dampening assembly for washing machine of the embodiment of the present invention, comprising: hanger bar 1, lower carriage 2, elastic component 3 and upper bracket 4.
Specifically, hanger bar 1 defines one axially.
Lower carriage 2 and hanger bar 1 time (namely indicated under arrow as shown in Figure 1 direction) are held and are connected.
Elastic component 3 to be socketed in hanger bar 1 and the lower end abutment lower carriage 2 of elastic component 3.Such as, elastic component 3 can be spring.
Upper bracket 4, described upper bracket 4 has compression face for contacting with bucket outer wall face, and described upper bracket 4 is located in described the hanger bar 1 and upper end of described elastic component 3 movably against described upper bracket 4.
Here it should be noted that, common washing machine comprises casing and is located at the staving in casing.When being installed on washing machine according to the suspension dampening assembly for washing machine of the embodiment of the present invention, lower carriage 1 is connected with casing and upper bracket 4 is connected with staving.When washing machine runs, because the rotation of staving can produce vibrations, and according to the suspension dampening assembly for washing machine of the embodiment of the present invention, the upper bracket that there is elastic component and be located at movably in hanger bar, described upper bracket is provided with the through hole suitable with described hanger bar, the relatively described axis of through hole of described upper bracket has the internal face 41 of two relative tilts, in order to rub to offset the shaking force produced when washing machine runs to produce with at least part of contact of the corresponding outside wall surface 11 of hanger bar after by the pressure of staving.
According to the suspension dampening assembly for washing machine of the embodiment of the present invention, as shown in Figure 2, the compression face 42 of described upper bracket 4 is spherical.
According to an example of the present invention, as shown in Figure 2, upper bracket 4 is provided with the through hole 41 suitable with hanger bar 1, and hanger bar 1 is socketed in hanger bar 1 to make upper bracket 4 through through hole 41.Further, the diameter of through hole 41 is not more than the external diameter of hanger bar 1, and such as, the diameter of through hole 41 can be slightly less than the external diameter of hanger bar 1.Thus, upper bracket 4 can be made more tight with coordinating of hanger bar 1, when more easily making upper bracket 4 move in hanger bar 1, produce damping friction between the two, the effect of offsetting staving shaking force is better.
Advantageously, lower carriage 2 and upper bracket 4 can be plastic stent.Further, lower carriage 2 and upper bracket 4 are by injection moulding integrated molding.Thus, shaping simple, cost is low.In addition, the upper bracket 4 of plastic material can also produce elastic deformation, further can offset shaking force.
