Describe the resilient suspension system 100 for washing machine according to the utility model embodiment below with reference to Fig. 1-Fig. 4, this resilient suspension system 100 may be used for vibration damping correction.
Suspension rod 1, damping sleeve 2, spring tray 3, first spring part group 41 and the second spring part group 42 can be comprised according to the resilient suspension system 100 of the utility model embodiment.As Figure 1-Figure 4, suspension rod 1 is communicated with in resilient suspension system 100 inside in order to carry the weight of whole dehydration barrel.Preferably, multiple suspension rod 1 can be set and multiple suspension rod 1 is evenly distributed on the circumference of dehydrating vessel in washing machine central shaft, thus, equally distributed suspension rod 1 not only can keep the balance of dehydrating vessel in washing machine, and multiple suspension rod 1 can carry the weight of dehydrating vessel in washing machine jointly, uniform stressed each other.
According to an embodiment of the present utility model, damping sleeve 2 to be set on suspension rod 1 and to fix with suspension rod 1.As Figure 1-Figure 4, it is inner that damping sleeve 2 can be arranged on resilient suspension system 100, sheathed and be fixed on suspension rod 1.When resilient suspension system 100 load, damping sleeve 2 can play certain buffer shock-absorbing effect.Alternatively, damping sleeve 2 has upper spring seat 21.The upper spring seat 21 be arranged on damping sleeve 2 can compress spring part 4 when load.
According to an embodiment of the present utility model, spring tray 3 to be set on suspension rod 1 and can axially moving on suspension rod 1 along suspension rod 1.As Figure 1-Figure 4, can simultaneously sheathed damping sleeve 2 and spring tray 3 on suspension rod 1, and damping sleeve 2 and spring tray 3 are separately positioned on the two ends of suspension rod 1.Damping sleeve 2 can be fixed on suspension rod 1, and spring tray 3 can along with the size of load, and the axis along suspension rod 1 moves around.Preferably, after the spring part 4 that the design height of spring tray 3 will meet resilient suspension system 100 usually kills, do not contact with damping sleeve 2.
Preferably, the first spring part group 41 and the second spring part group 42 that stiffness factor K is different can be set in resilient suspension system 100 inside, thus make resilient suspension system 100 have good vibration damping correction work in order to meet demand during different loads.Preferably, each spring part 4 of the first spring part group 41 is connected between spring tray 3 and upper spring seat 21, one end of each spring part 4 of the second spring part group 42 is fixed on spring tray 3, its other end is that free end and upper spring seat 21 are oppositely arranged and spaced apart, that is, the length of the spring part 4 of the first spring part group 41 is than the length of the spring part 4 of the second spring part group 42.
When resilient suspension system 100 increases load gradually, the spring part 4 of the first spring part group 41 shortens gradually because being subject to certain compression stress, and the stiff end of the spring part 4 of the second spring part group 42 is along with spring tray 3 moving axially along suspension rod 1, its free end is then gradually near upper spring seat 21, until be resisted against on upper spring seat 21, finally shorten because of the increase of load.When resilient suspension system 100 reduces load gradually, each spring part 4 of the first spring part group 41 and the second spring part group 42 increases until reinstatement gradually because of the elastic-restoring force of self.
According to the resilient suspension system 100 of the utility model embodiment, the noise control vibration damping that can effectively realize under unloaded and fully loaded two states by arranging the first spring part group 41 and the second spring part group 42 is rectified a deviation, thus be beneficial to the normal operation of complete machine, increase the service life of washing machine.
According to an embodiment of the present utility model, resilient suspension system 100 can also comprise base 5, and as shown in Figure 1, when resilient suspension system is in free state, the bottom of spring tray 3 can be resisted against on base 5.
In concrete example of the present utility model, the length of multiple spring part 4 is different.Preferably, the length of multiple spring part 4 reduces successively according to direction from inside to outside, and that is, the first spring part group 41 is positioned at inner side, and the second spring part group 42 is positioned at outside.Thus, when resilient suspension system 100 increases load gradually, be positioned at spring part 4 load at first of the first spring part group 41 of inner side, along with the increase gradually of load, the spring part 4 of the first spring part group 41 is compressed power and shortens gradually, the spring part 4 being positioned at the second spring part group 42 in outside starts load, as Figure 3-Figure 4.
According to an embodiment of the present utility model, the radial dimension of multiple spring part 4 is different and be from inside to outside enclosed within the outside of suspension rod 1 coaxially.The spring part 4 of different radial dimension can have different stiffness factors, and the ability of load is also different.Preferably, the stiffness factor K of multiple spring part 4 increases gradually according to direction from inside to outside.Thus, the stiffness factor of the spring part 4 that the length inside being positioned at is the longest is minimum, and load capacity is the most weak, and the stiffness factor being positioned at the shortest spring part of length of outer side 4 is maximum, and load capacity is the strongest.
According to an embodiment of the present utility model, multiple spring part 4 is coaxially arranged, that is the spring part 4 of the first spring part group 41 and the second spring part group 42 is coaxial distributions, and the spring part 4 of the first spring part group 41 and the second spring part group 42 can arrange multiple respectively and be evenly distributed on a week of suspension rod 1.Further preferably, spring part 4 can comprise inner ring spring part 41 and cycle spring part 42.Such as, inner ring spring part 41 can be the spring part 4 being positioned at inner side, and cycle spring part 42 can be outermost spring part 4.First spring part group 41 with in the second spring part group 42 often to organize the stiffness factor of spring part 4, radial dimension and length identical respectively, stiffness factor, radial dimension and length between the spring part 4 of different group can be different.
According to an embodiment of the present utility model, between two adjacent spring parts 4, be provided with the dividing plate 6 of annular.That is, dividing plate 6 is around in one week of suspension rod 1 ringwise to be separated by adjacent two groups of spring parts 4, thus prevents adjacent springs part 4 distortion that causes because of stressed flexural deformation together.
According to the washing machine of the utility model another aspect embodiment, the resilient suspension system 100 for washing machine in above-described embodiment can be comprised.
In the description of this description, specific features, structure, material or feature that the description of reference term " embodiment ", " some embodiments ", " example ", " concrete example " or " some examples " etc. means to describe in conjunction with this embodiment or example are contained at least one embodiment of the present utility model or example.In this manual, to the schematic representation of above-mentioned term not must for be identical embodiment or example.And the specific features of description, structure, material or feature can combine in an appropriate manner in any one or more embodiment or example.In addition, the different embodiment described in this description or example can carry out engaging and combining by those skilled in the art.
Although illustrate and described embodiment of the present utility model above, be understandable that, above-described embodiment is exemplary, can not be interpreted as restriction of the present utility model, those of ordinary skill in the art can change above-described embodiment, revises, replace and modification in scope of the present utility model.
