Detailed description of the invention
Be described below in detail embodiment of the present utility model, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Be exemplary below by the embodiment be described with reference to the drawings, be intended to for explaining the utility model, and can not be interpreted as restriction of the present utility model.
Below with reference to Fig. 1, the balance weight 100 for washing machine according to the utility model first aspect embodiment is described.
As shown in Figure 1, according to the balance weight 100 for washing machine of the utility model first aspect embodiment, in balance weight 100, be formed with multiple cavity 1, in each cavity 1, be provided with multiple damping particles 2.
Particularly, multiple cavity 1 is spaced to turn up the soil and is distributed in balance weight 100, each cavity 1 is all formed as independent and airtight chamber, wherein any two cavitys 1 are not connected, and any one cavity 1 does not all communicate with the outside of balance weight 100, be equipped with multiple damping particles 2 in each cavity 1, preferably, each damping particles 2 can be formed as spheroidal, and the diameter of the damping particles 2 of each spheroidal is preferably 0.05mm-5mm.Certainly, the utility model is not limited thereto, and shape, the size of damping particles 2 can also be arranged according to actual requirement, to meet actual requirement better.
Further, the cumulative volume of the multiple damping particles 2 in each cavity 1 is 70% ~ 80% of the volume of corresponding cavity 1, thus ensures the space all in each cavity 1 with damping particles 2, makes cavity 1 be in non-blocking state.Thus, along with the vibration of balance weight 100, continuous inelastic collision and friction is all produced between damping particles 2, between damping particles 2 and the inwall of cavity 1, thus can vibrational energy be consumed, reach the object of vibration damping, and by arranging multiple cavity 1, can the overall friction increasing particle and cavity 1 wall, thus increase damping vibration attenuation, noise reduction further.
Alternatively, damping particles 2 can be metallic particles or non-metallic particle, and the proportion of damping particles 2 is larger, effectiveness in vibration suppression better, and preferably, damping particles 2 is steel particles.
According to the balance weight 100 for washing machine of the utility model embodiment, by arranging multiple cavity 1 with damping particles 2 in balance weight 100, thus utilize the damping vibration attenuation effect of particle damping fully, effectively consume the vibrational energy of washing machine in the whole water smoking, reduce the amplitude of washing machine, improve the vibrating noise problem of washing machine.In addition, adopt particle damping when can change very little at traditional balance weight 100, thus effectively improve the damping ratio of structure when substantially not producing additional mass, realize vibration damping, noise reduction.
In an embodiment of the present utility model, each cavity 1 can extend along the width of balance weight 100, and be formed as cylindrical, such as in the example of fig. 1, multiple cavity 1 is all configured to cylindrical, and the central axis of multiple cylindrical cavity 1 is parallel respectively, the central axis of each cavity 1 is all identical with the bearing of trend of balance weight 100 width, thus the space that can increase in the quantity of balance weight 100 internal cavity 1 and each cavity 1, with the problem avoiding damping particles to pile up in cavity 1, guarantee damping particles 2 can in individual cavity 1 sufficient movement, to improve damping vibration attenuation effect, in addition, tubular cavity 1 can improve vibration number and the friction effect of damping particles 2 effectively, and be convenient to processing.
In the process of processing, Mould Machining first can be adopted to go out to have the balance weight 100 of multiple dead slot, and then in dead slot, fill the damping particles 2 of some, then adopt cement or fluid sealant etc. to be sealed by the open end of dead slot.Thus, be cavity 1 by the dead slot sealed, the filling rate of the damping particles 2 of filling in cavity 1 is preferably 70%.
Certainly, the utility model is not limited thereto, and the quantity of cavity 1, shape and size can also be arranged according to actual requirement, and to meet actual requirement better, such as cavity 1 can also be configured to spheroidal, elliposoidal and polyhedron shape etc.Preferably, multiple cavity 1 is evenly distributed on balance weight 100.Thus, effectiveness in vibration suppression can be improved.
According to the washing machine (scheming not shown) of the utility model second aspect embodiment, comprise outer barrel (scheming not shown) and the balance weight 100 for washing machine according to the above-mentioned first aspect embodiment of the utility model, balance weight 100 is located in outer barrel.
Such as in an example of the present utility model, washing machine can also comprise: body (scheming not shown) and interior bucket (scheming not shown), wherein, interior bucket is located in outer barrel rotationally, outer barrel is suspended in body, balance weight 100 can be fixed on the bottom of outer barrel periphery wall, preferably, balance weight 100 can be formed with multiple installing hole run through, multiple installing hole and multiple cavity 1 are spaced apart from each other, correspondingly, the periphery wall of outer barrel is provided with connecting portion (scheming not shown), connecting portion is formed with multiple connecting hole, connecting hole and installing hole one_to_one corresponding, thus by multiple threaded fastener 3, multiple connecting hole and multiple installing hole can be linked together, and then balance weight 100 can be fixed on the periphery wall of outer barrel.
Like this, washing machine is in the process of dehydration, and during interior bucket low speed rotation, the balance weight 100 with damping particles 2 can reduce the amplitude at suspension resonance point place, thus improve the anti-eccentric ability of washing machine, the displacement effectively improving tub-impact phenomenon and washing machine is walked problem; Along with the rising of rotating speed, when interior bucket High Rotation Speed, the motion of damping particles 2 is more violent, thus can consume the vibrational energy of outer barrel, reduces the complete machine oscillation of washing machine.Thus, washing machine is in the process of whole dehydration, and balance weight 100 all can play vibration damping, noise reduction effectively, makes the vibration of complete machine less, improves the anti-vibration of product, low noise properties.Wherein, suspension is prior art.
