The specific embodiment
Hereinafter, describe in detail with reference to the accompanying drawings according to exemplary embodiment of the present invention.
Hereinafter, referring to figs. 1 through 3 dynamic dampers 100 of describing the first-1 exemplary embodiment according to the present invention.
The washing machine W1 of first exemplary embodiment according to the present invention hereinafter, is described with reference to Fig. 1 and 2.Fig. 1 and 2 illustrates dynamic damper according to the present invention and is connected to tumbling-box washing machine, and still, washing machine according to the present invention is not limited to tumbling-box washing machine.Dynamic damper according to the present invention can be applicable to the washing machine of all on-stream generation vibrations, can be used for the agitator type washing machine with the eddy current washing clothes that produces in the bucket equally.Therefore, dynamic damper according to the present invention is not limited to tumbling-box washing machine, but comprises all types of washing machines that produce vibrations when turning round.
Washing machine W1 comprises: casing 2, the outward appearance of formation washing machine 1; Washtub 40 is arranged in the casing 2, is used to deposit slurry, and the space of washing clothes is provided; Drive source 5 is installed in the rear side of cylindric washer 40, is used for driving force is sent to cylindric washer 40; Cabinet cover 8 is installed in the front portion of casing 2, and the heart has door part 9 therein, and described cabinet cover 8 is used to form casing 2, and door 10 can be rotatably set in the cabinet cover 8, thus the door part 9 of open and close cabinet cover 8; With dynamic damper 100, connect the bottom surface 8e of casing 2.
Among Fig. 1, dynamic damper 100 is connected in the casing 2, still, dynamic damper 100 can be arranged in any position that the vibrations of washing machine can be sent to, and the position of dynamic damper 100 is not limited to casing inside, if transmit vibrations, then dynamic damper 100 does not need directly to contact casing.And, according to the present invention, because dynamic damper according to the present invention forms with module, and be connected to washing machine W1, therefore, though dynamic damper is connected to the outside of washing machine, but dynamic damper has the very little fault and the possibility of damage, and graceful outward appearance is provided.The element and the function of dynamic damper 100 described in the back.
Washtub 40 comprises: bucket 30 is arranged in the casing 2 by spring 12A and damper 12B buffering, and is used to deposit slurry; Cylinder 20, be arranged in the bucket 30, thereby by drive source 5 rotations, and be used for accommodating laundry, in this cylinder, form a plurality of hole 20A that are used for by slurry, with lifter 22, be arranged in the cylinder 20, thereby when cylinder 20 rotations, after clothing is risen to predetermined altitude, clothing is fallen by gravity.
Because washtub 40 only is used for tumbling-box washing machine, therefore washtub 40 comprises cylinder and bucket, but, in the washing machine of other types, for example, agitator type washing machine, because washtub 40 comprises the agitator that is used to deposit the water tank of slurry and produces eddy current in water tank, therefore washtub according to the present invention is not limited thereto.And door part 9 does not need always to be arranged on the front, can be arranged on upper surface yet, that is, the position of door is not limited to above-mentioned position.
When being described below, the washing machine running produces the reason of vibrations.
One end of the cylinder 20 in washtub 40 should directly or indirectly be connected to drive source 5, thereby receives the rotary power that transmits from drive source 5.But because the other end of cylinder 20 is connected to spring 12A and damper 12B, therefore, the other end of cylinder 20 hangs by gravity at gravity direction.Because this hang, the center of gravity of cylinder 20 away from the rotating shaft of cylinder 20, therefore, when cylinder 20 rotations, shake because uneven Mass Distribution produces.Even washing machine is not a tumbling-box washing machine, owing to be arranged in the heterogeneity of the clothing in the washtub, or the heterogeneity of inner member, when washing machine turns round, can produce sizable vibrations.Thereby such vibrations can further be discussed in rotating the process of clothes dewatering at a high speed at cylinder, thereby when the running washing machine, in dehydration, vibrations are considered to sixty-four dollar question especially.
Because architectural characteristic, the possibility that tumbling-box washing machine W1 produces vibrations is big, but vibration problems is not limited to tumbling-box washing machine.For fear of being repeated in this description, washing machine is limited to tumbling-box washing machine W1, and will describe the function according to damping device of the present invention.But those skilled in the art should understand, and produces in the every other washing machine of vibrations when dynamic damper according to the present invention can be used for turning round.
The dynamic damper 100 (hereinafter, the dynamic damper that is used for washing machine is called dynamic damper) of the washing machine W1 be connected to the first-1 exemplary embodiment according to the present invention is described with reference to Fig. 3 hereinafter.
In this exemplary embodiment, elastomer 120 comprises first elastomer 122 and second elastomer 124.Elastomer 120 can be arranged like this: when the inertia force of the quality body 110 that produces when quality body 110 vibrations affacts first elastomer 122 with pressure, the inertia force of quality body 110 with tension to second elastomer 124.In Fig. 1, first elastomer 122 supports the first end 112 of quality body, and the second end 114 of second elastomer, 124 support quality bodies, and still, this is an example, and scope of the present invention is not limited to the elastomeric structure shown in Fig. 1.Elastomer 120 can be the wind spring of Fig. 3, but elastomer 120 is not limited thereto.If elastomer 120 has elastic-restoring force, thus the vibrations that produce the quality body, then elastomer 120 can use the spring of other kinds, for example extension spring and leaf spring and wind spring, and can use any rubber-like material.
The reason that the dynamic damper 100 of first exemplary embodiment can effectively reduce washing machine vibrations according to the present invention is described with the vibrant characteristic of washing machine hereinafter.
As mentioned above, in washing machine W1, produce sizable vibrations.Therefore need damping device.As such device, as shown in Figure 2, spring 12A and damper 12B support washtub 40, still, only use such device to come damping to have limitation, and because the vibrant characteristic of washing machine, vibrations increase sometimes.Therefore, in order to obtain the damping of enough degree, consider independent damping device.
According to physical principle, the intrinsic frequency of washing machine with
Proportional, wherein m is the quality of vibration body, and k is an elastic modelling quantity.Be connected to washing machine and produce resonance if having the object of the intrinsic frequency identical with the intrinsic frequency of washing machine, then the vibrations of washing machine reduce.This is the physical law as the dynamic damper theoretical background, and is conventionally known to one of skill in the art.Therefore, by using such physical law as theoretical background, be designed for the dynamic damper that reduces the washing machine vibrations.
But, only use such physical background, the vibrations that can not design immediately and can be applied to product immediately, produce during simultaneously with the real-world operation washing machine are reduced to the dynamic damper of enough degree.
Usually, obtain elastic modelling quantity by experiment according to the washing machine vibrant characteristic, can determine the intrinsic frequency of washing machine, and be connected to washing machine by the elastomer that will have the intrinsic frequency similar to the intrinsic frequency of washing machine, according to the basic theories of dynamic damper, can obtain damping to a certain degree.But, for such dynamic damper is applied to product, need be about the more thorough research of washing machine vibrant characteristic, but and need and satisfy for example tuning, productivity ratio and the dynamic damper of all factors such as cost with other element absorbing vibrations of washing machine.This is because the vibrations that produce in the washing machine are major issues, though vibrations reduce, if produce surcharge or work on hand deterioration of efficiency, then is difficult to select such device, and the quality competition power of washing machine is applied negative effect.Therefore, need to consider the vibrant characteristic of washing machine carefully, and design the optimization dynamic damper that minimizes additional trouble, reduces to shake according to vibrant characteristic simultaneously.
Under such theoretical background, the vibrant characteristic that research is used to develop the washing machine of optimizing dynamic damper is described below.
At first, when cylinder 20 rotated with high speed, the vibrations of washing machine became big problem.That is, because the energy of vibrations object is square proportional with amplitude and frequency, therefore when rotating at a high speed, vibration energy increases, and thereby the problem increase relevant with vibrations.But when drive source was supplied with washing machine with the high speed rotary power, washing machine carried out dehydration usually.Rotary power can change according to the specification and the driving situation of washing machine, but, because drive source provides the rotary power with about 900-1100rpm revolution in dehydration, therefore preferred dynamic damper is designed for the vibrations that reduce generation when rotating with such high speed.
Because washing machine uses by being fixed to ground E, therefore the vibrations that produce in washing machine are sent to ground E.Therefore, the vibrations of washing machine should be considered with the process that vibrations are sent to ground E.
The vibrations that produce during the washing machine running are not limited to a direction usually.Based on the ground E of support washing machine, the three-dimensional shock motion that is not subjected to vertical direction, fore-and-aft direction and laterally limits.But, if when for example carrying out running such as dehydration when washing machine, transmit the high speed rotary power from drive source, then the frequency of washing machine produces resonance thus near the intrinsic frequency of ground E.Such resonance results from the dehydration of drive source with rotation at a high speed usually especially.But, because E when vibrations shock motion in ground is at fore-and-aft direction and laterally be restricted, amplitude is bigger, and owing to do not have the structure that limits ground E shock motion along the vertical direction that shakes, so the moving motion of the principal earthquake of ground E is the shock motion of vertical direction.Therefore, as in the dehydration of washing machine, when when high-frequency range shakes, owing to shake with ground E, the moving motion of the principal earthquake of washing machine accumulates in the vertical direction of shock motion.Therefore, in order to reduce the vibrations in the dehydration, it is the subject matter in the vibrations, considers the vibrant characteristic of such vertical direction, needs damping device.
Under such theoretical background, dynamic damper 100 according to the present invention can be connected to the bottom surface 8e of washing machine W1, thereby the quality body 110 of dynamic damper 100 vertically, be the direction vibrations of gravity effect, with when washing machine W1 and ground E produce resonance, reduce the vibrations that vertically produce in the resonant process.When washing machine turned round, when the dynamic damper 100 of layout and ground resonance, the vibrations of generation were reduced effectively.
