Below with reference to Fig. 1-Fig. 4, the resilient suspension system 100 for washing machine according to embodiments of the present invention, this elasticity are described
Suspension 100 may be used for vibration damping correction.
Resilient suspension system 100 according to embodiments of the present invention can include suspension rod 1, damping sleeve 2, spring tray 3, first
Spring part group 41 and the second spring part group 42.As Figure 1-Figure 4, suspension rod 1 connects inside resilient suspension system 100
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 laundry
The circumference of machine dehydration barrel central shaft, thus, equally distributed suspension rod 1 not only can keep the balance of dehydrating vessel in washing machine, and
Multiple suspension rods 1 can carry the weight of dehydrating vessel in washing machine, uniform stressed each other jointly.
According to one embodiment of present invention, damping sleeve 2 is set on suspension rod 1 and fixes with suspension rod 1.Such as Fig. 1-Fig. 4 institute
Showing, it is internal that damping sleeve 2 can be arranged on resilient suspension system 100, sheathed and be fixed on suspension rod 1.When resilient suspension system
During 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 being arranged on damping sleeve 2 can compress spring part 4 when load.
According to one embodiment of present invention, spring tray 3 is set on suspension rod 1 and can axial at suspension rod 1 along suspension rod 1
Upper movement.As Figure 1-Figure 4, on suspension rod 1 can the most sheathed damping sleeve 2 and spring tray 3, and damping sleeve 2 He
Spring tray 3 is separately positioned on the two ends of suspension rod 1.Damping sleeve 2 can be fixed on suspension rod 1, and spring tray 3 is permissible
Along with the size of load, along axially moving back and forth of suspension rod 1.Preferably, the design height of spring tray 3 generally to be expired
After the spring part 4 of foot resilient suspension system 100 kills, do not contact with damping sleeve 2.
Preferably, the first different for stiffness factor K spring part groups 41 and second can be set inside resilient suspension system 100
Spring part group 42, so that resilient suspension system 100 has good vibration damping correction effect 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, the second bullet
One end of each spring part 4 of spring part group 42 is fixed on spring tray 3, and its other end is free end and upper spring seat 21
It is oppositely arranged and spaced apart, say, that the length of the spring part 4 of the first spring part group 41 is than the second spring part group 42
The length of spring part 4.
When resilient suspension system 100 is gradually increased load, the spring part 4 of the first spring part group 41 is because of by certain compression
Power gradually shortens, and the fixing end of the spring part 4 of the second spring part group 42 is along with spring tray 3 is along the axial shifting of suspension rod 1
Dynamic, its free end then moves closer to upper spring seat 21, until being resisted against on upper spring seat 21, finally because of the increase of load
Shorten.When resilient suspension system 100 is gradually reduced load, the first spring part group 41 and the second spring part group 42 each
Spring part 4 gradually increases until reinstatement because of the elastic-restoring force of self.
Resilient suspension system 100 according to embodiments of the present invention, by arranging the first spring part group 41 and the second spring part group 42
The noise control vibration damping correction can being effectively realized under unloaded and fully loaded two states, thus beneficially complete machine is properly functioning, increases
The service life of washing machine.
According to one embodiment of present invention, resilient suspension system 100 can also include base 5, as it is shown in figure 1, when elasticity
When suspension is in free state, the bottom of spring tray 3 can be resisted against on base 5.
In the concrete example of the present invention, the length of multiple spring parts 4 is different.Preferably, the length of multiple spring parts 4 is pressed
It is sequentially reduced according to direction from inside to outside, say, that the first spring part group 41 is positioned at inner side, the second spring part group 42
In outside.Thus, when resilient suspension system 100 is gradually increased load, it is positioned at the spring of the first spring part group 41 of inner side
Part 4 loads at first, and along with being gradually increased of load, the spring part 4 of the first spring part group 41 is gradually shortened by compression stress,
The spring part 4 of the second spring part group 42 being positioned at outside then starts load, as Figure 3-Figure 4.
According to one embodiment of present invention, the radial dimension of multiple spring parts 4 is different and is enclosed within suspension rod 1 the most coaxially
Outside.Different radial dimension of spring parts 4 can have different stiffness factors, and the ability of load is the most different.
Preferably, the stiffness factor K of multiple spring parts 4 is gradually increased according to direction from inside to outside.Thus, the length of inner side it is positioned at
The stiffness factor spending the longest spring part 4 is minimum, and load capacity is the most weak, is positioned at the stiffness of the shortest spring part of length of outer side 4
Coefficient is maximum, and load capacity is the strongest.
According to one embodiment of present invention, multiple spring parts 4 are coaxially arranged, say, that the first spring part group 41 and second
The spring part 4 of spring part group 42 is coaxial distribution, and the spring part 4 of the first spring part group 41 and the second spring part group 42 can
To be respectively provided with multiple and to be evenly distributed on a week of suspension rod 1.It is further preferred that spring part 4 can include interior coil spring
Part 41 and cycle spring part 42.Such as, inner ring spring part 41 can be in the spring part 4 of inner side, cycle spring part
42 can be outermost spring part 4.The strength often organizing spring part 4 in first spring part group 41 and the second spring part group 42
Degree coefficient, radial dimension are the most identical with length, stiffness factor, radial dimension and the length between the spring part 4 of different groups
Can be different.
According to one embodiment of present invention, the dividing plate 6 of annular it is provided with between two adjacent spring parts 4.That is, dividing plate 6
Enclose ringwise one week that is located at suspension rod 1 so that two groups of adjacent spring parts 4 are separated, thus prevent because stress flexural deformation causes
Adjacent springs part 4 distort together.
The washing machine of embodiment according to a further aspect of the invention, can include the elastic suspended for washing machine in above-described embodiment
Extension system 100.
