Below with reference to Fig. 1 and Fig. 2 the damping device 10 that is used for washing machine according to the utility model embodiment is described.As depicted in figs. 1 and 2, the damping device 10 that is used for washing machine according to the utility model embodiment comprises suspension rod 100, sleeve 200 and variable-pitch spring 300.
Sleeve 200 is located on the suspension rod 100 movably.One end of variable-pitch spring 300 links to each other with suspension rod 100 and the other end of variable-pitch spring 300 links to each other with sleeve 200.Wherein variable-pitch spring 300 is the unequal spring of pitch.
By the variable-pitch spring 300 that links to each other with sleeve 200 with suspension rod 100 is set respectively, can utilize the character of linear Stiffness variation of variable-pitch spring 300 to adapt to the washing clothes of Different Weight according to the damping device 10 that is used for washing machine of the utility model embodiment.Particularly, when the load of variable-pitch spring 300 hour, the stiffness coefficient of variable-pitch spring 300 is a little value.When the load of variable-pitch spring 300 was larger, the stiffness coefficient of variable-pitch spring 300 was a large value.The rigidity that is variable-pitch spring 300 increases along with the increase of load.Have the washing machine of damping device 10 when operation, if clothing is less, then the load of variable-pitch spring 300 is less, and the rigidity of variable-pitch spring 300 is less.If clothing is more, then the load of variable-pitch spring 300 becomes large, and it is large that the rigidity of variable-pitch spring 300 becomes, and can prevent thus the washing machine shell distortion, guarantee that the position sinking within reason of wash bucket is with conserve space.Because the rigidity of variable-pitch spring 300 is indefinite, therefore there is not traditional intrinsic frequency, the centrifugal force because of off-centre in the time of can avoiding laundry machine dehydration thus produces resonance and noise.In addition, the stiffness coefficient of variable-pitch spring 300 remains the minimum of a value of certain loads, can effectively reduce like this when dehydration be delivered on the washing machine shell exciting force, reach damping and reduce the effect of noise.And the washing machine with damping device 10 need not thickness and the volume of housing are increased, thereby can significantly reduce the production cost of washing machine.Therefore, the damping device 10 that is used for washing machine according to the utility model embodiment has vibration and the noise that can prevent the washing machine shell distortion, reduce washing machine, the advantages such as cost of the space availability ratio of raising washing machine, reduction washing machine.
Particularly, as shown in Figure 2, variable-pitch spring 300 can comprise the first spring section 310 with first segment distance at least, and the second spring section 320 with second section distance, and wherein the first segment distance can be less than the second section distance.Can prevent further that thus washing machine shell is out of shape, reduces vibration and the noise of washing machine, improves the space availability ratio of washing machine.
More specifically, as shown in Figure 2, variable-pitch spring 300 can comprise that two the first spring sections 310 and the second spring section 320, the second spring sections 320 can be between two the first spring sections 310.In other words, two the second spring sections 320 can lay respectively at the both ends of variable-pitch spring 300, and the first spring section 310 can be positioned at the middle part of variable-pitch spring 300.That is to say, the pitch at the both ends of variable-pitch spring 300 can be less than the pitch at the middle part of variable-pitch spring 300.The rule that the rigidity of variable-pitch spring 300 is changed with load is suitable for the requirement of washing machine more, thereby can further prevent the washing machine shell distortion, reduce vibration and the noise of washing machine, improves the space availability ratio of washing machine.
Fig. 1 shows the damping device 10 that is used for washing machine according to an embodiment of the utility model.As shown in Figure 1, sleeve 200 is interior can to have the container cavity 210 that the lower end is opened wide, and can be provided with central through hole 211 on the roof of container cavity 210, and suspension rod 100 can pass central through hole 211, and suspension rod 100 can matched in clearance with central through hole 211.Sleeve 200 can be located on the suspension rod 100 movably thus, and the Stability Analysis of Structures of sleeve 200 and suspension rod 100, cooperate reliable.
Alternatively, as shown in Figure 1, variable-pitch spring 300 can be set on the suspension rod 100 and variable-pitch spring 300 can be positioned at container cavity 210.So not only can improve the stability of the position of variable-pitch spring 300, and can utilize sleeve 200 protection variable-pitch springs 300, be used in the outward appearance neat appearance more of the damping device 10 of washing machine.
Fig. 1 shows the damping device 10 that is used for washing machine according to a specific embodiment of the utility model.As shown in Figure 1, the lower end of suspension rod 100 can be provided with spring base 110, and the upper end of variable-pitch spring 300 can be against on the roof of container cavity 210 and the lower end of variable-pitch spring 300 can be against on the spring base 110.An end of variable-pitch spring 300 can be connected to indirectly on the suspension rod 100 like this and the other end is connected on the sleeve 200 to realize the function of load-bearing and damping, and the Stability Analysis of Structures between variable-pitch spring 300, suspension rod 100 and the sleeve 200 can improve the reliability of the performance of variable-pitch spring 300 thus.
Particularly, as shown in Figure 1, can be provided with center mounting hole on the spring base 110, the lower end of suspension rod 100 can be provided with mounting cap 120, suspension rod 100 can pass described center mounting hole and mounting cap 120 can backstop on the lower surface of spring base 110.Can utilize like this mounting cap 120 on above-below direction, spring base 110 to be positioned, spring base 110 can be fixed on thus on the suspension rod 100 to prevent that spring base 110 relative suspension rods 100 from moving down, thereby can improve the stability for the damping device 10 of washing machine, and simple in structure, the handling ease of suspension rod 100.
Fig. 1 shows the damping device 10 that is used for washing machine according to a concrete example of the utility model.As shown in Figure 1, the lower end of sleeve 200 can be provided with outward flange 220.Thus can be by wash bucket being connected on the outward flange 220 wash bucket is installed on the whole damping device 10, namely can be used in damping device 10 easier for installation of washing machine.
Advantageously, as shown in Figure 1, can arc transition between the periphery wall of outward flange 220 and sleeve 200.Can further improve thus for the damping device 10 of washing machine and the convenience that is connected of wash bucket.
More advantageously, outward flange 220 can be formed on the sleeve 200.So not only can strengthen the intensity of sleeve 200, and can simplify the production technology of sleeve 200, thereby can reduce the production cost of sleeve 200.
Washing machine according to the utility model embodiment is described below, and described washing machine comprises housing (not shown), wash bucket (not shown) and damping device.
Has container cavity in the described housing.Described wash bucket is located in the described container cavity.Described damping device is the damping device 10 that is used for washing machine according to the utility model above-described embodiment, and suspension rod 100 links to each other with described housing and sleeve 200 links to each other with described wash bucket.
According to the washing machine of the utility model embodiment by utilizing the damping device 10 that is used for washing machine according to the utility model above-described embodiment, thereby have not yielding, vibration and noise little, space availability ratio is high, low cost and other advantages.
