The specific embodiment
When combining with accompanying drawing according to following detailed description of the present invention can know more more than of the present invention with other purpose, characteristic, aspect and advantage.Describe exemplary embodiment of the present invention in detail referring now to accompanying drawing.Yet the present invention can be by with a lot of different embodied and should not be understood that to be subject to the embodiment that sets forth here.In fact, will be completely and completely thereby these embodiment disclosure are provided, and will express scope of the present invention to those skilled in the art fully.In the drawings, shape and size possibly for the sake of clarity exaggerated, and will in full text, use same reference numerals to mark identical or similar member.
Fig. 1 is the side sectional view of washing machine according to an exemplary embodiment of the present invention.Fig. 2 is the zoomed-in view of the part " A " among Fig. 1.Fig. 3 is outer barrel the front view of in Fig. 1, illustrating.Fig. 4 is the cross sectional view of the part " B " among Fig. 3.Fig. 5 is the zoomed-in view of the part " C " among Fig. 3.
Usually; Outside forming with uniform thickness during bucket 120 sidewall (hereinafter; Outer bucket with outer wall of having uniform thickness will be known as " relatively body "), confirm the thickness of the sidewall of comparison body for the weight of washing machine with corresponding to the rigidity of the vibration characteristics of generation when interior bucket 115 rotations with taking in.In this case, the state that is present in the comparison body in clothes and rinse water is confirmed thickness for overall load with taking in.Relatively the sidewall of body must be formed in its any part and bear overall load.Therefore, the bottom with the sidewall of load centralization forms the thickness with 2.4mm if desired, then totally should form the relatively sidewall of body with 2.4mm or bigger uniform thickness.
Under the same conditions, in order to keep abundant rigidity, the thickness of the bottom of the sidewall sections 122 of outer bucket 120 must be 2.4mm or bigger according to an exemplary embodiment of the present invention.With reference to Figure 4 and 5, the thickness that sidewall sections 122 is formed its top is that the thickness of 1.5mm and bottom is 3.5mm.That is to say; Because the bottom of sidewall sections 122 has the thickness greater than the 3.5mm of 2.4mm; So can guarantee abundant rigidity; And in this case, though the top of the sidewall sections 122 that load is concentrated has the thickness less than the 1.5mm of 2.4mm lessly, it can realize abundant rigidity.Just, according to an exemplary embodiment of the present, even because have this little thickness, abundant rigidity also can be guaranteed in top, thus the reduction of the thickness on the top of sidewall sections 122, and the thickness of the bottom of increase load centralization is to realize abundant rigidity.That is to say that the thickness of the upper and lower through making sidewall sections 122 is different, overall weight can be equal to or less than the comparison body.Therefore, outside with the made of same amount during bucket 120, compare with body relatively, outer according to an exemplary embodiment of the present invention bucket 120 can advantageously be guaranteed better rigidity.
Specifically; Consider that the consistent weight of trend that more and more has big capacity with outer bucket increases; Bucket 120 outside forming according to an exemplary embodiment of the present invention with the suitable difference in the thickness of sidewall sections 122; Therefore compare with comparing body, having reduced the weight that causes along with the capacity increase increases.That is to say, in the situation that compares body, because the thickness of sidewall is uniform; So weight increases according to capacity inevitably and increases pro rata with specific ratios, but comparatively speaking, according to an exemplary embodiment of the present invention outside in barrels 120 the situation; The thickness of the upper and lower through suitably regulating sidewall sections 122; Increasing the weight increase that causes according to capacity can relatively be reduced, thereby for capacity increased, this was favourable.
And; Because the bottom of sidewall sections 122 is heavier than the top of sidewall sections 122, so the contrast that forms with uniform thickness with sidewall sections 122, center of gravity forms in the bottom; And in view of the above, can keep stability about the vibration that when interior bucket 115 rotates, produces.And because can increase the rotary speed of interior bucket 115 owing to improved stability, institute is so that cleaning performance strengthens.Specifically, because can be with bucket 115 in the higher speed rotation, so the spin drying property can be able to improve.Simultaneously, thus can be outside forming rib 124 on the bucket 120 guarantees stronger rigidity.Rib 124 can be formed along vertical direction and be microscler, thereby prevents effectively to cause that owing to the difference in thickness of upper and lower rigidity reduces.
Sidewall sections can be formed and have the thickness that increases gradually from the bottom of the top outward bucket 120 of outer bucket 120 according to an exemplary embodiment of the present invention.Hereinafter, will propose two instances, wherein thickness increases from the bottom of the top outward bucket of outer bucket gradually.
Fig. 6 is the front view of the outer bucket of another exemplary embodiment according to the present invention.Fig. 7 is the cross sectional view of the part " D " among Fig. 6.
With reference to figure 6 and 7, thereby the sidewall sections 222 of the outer bucket 220 of another exemplary embodiment is formed with the slope thickness increases continuously from top towards the bottom according to the present invention.The bottom that the top of sidewall sections 222 has thickness d 1 and a sidewall sections 222 has thickness d 2 (d1＜d2).That is to say that sidewall sections 222 is formed thickness and increases continuously (just, from d1 to d2) from top towards the bottom.In this case, it is linear that the variation of thickness from d1 to d2 can need not to be, and the sidewall sections 222 of outer bucket 220 can be formed with various slopes when its thickness increases continuously.
Have the thickness that increases continuously because the cross section of sidewall sections 222 is formed, be applied to the load of sidewall sections 222, thereby can prevent the generation of abnormal vibrations or issuable crackle when load is concentrated in the particular location so can distribute.And, outside molded during bucket 220, can be easily with it from mold separation.
With reference to figure 7, when sidewall sections 222 is formed when having uniform thickness the center of gravity (M of sidewall sections 222
0) will be positioned at essentially identical distance 11 places apart from the upper and lower.Yet, as relatively, in of the present invention exemplary embodiment, because the thickness of sidewall sections 222 increases with constant slope towards the bottom from top gradually, so center of gravity (M) is positioned at the downside place, thus the stability of realization.
Fig. 8 is the front view of the outer bucket of the another exemplary embodiment according to the present invention.Fig. 9 is the cross sectional view of the part " E " among Fig. 8.With the explanation of omitting or similar structure identical with the above-mentioned exemplary embodiment of the present invention.
The outer bucket 320 of another exemplary embodiment is different from above-mentioned exemplary embodiment part and is thickness discontinuous increase towards the bottom from top of the outer wall section 322 of outer bucket 320 according to the present invention.
That is to say that as shown in fig. 9, sidewall sections 322 has stepped cross-section, have from top the thickness of discontinuous increase towards the bottom.Particularly, top has thickness w1 and bottom and has thickness w2 greater than w1 (w1＜w2), and stepped cross-section is formed in and exists each all to have the specific interval of the thickness value between thickness w1 and thickness w2 between the upper and lower.And, in this case, the center of gravity (N that has the situation of uniform thickness with sidewall sections 322
0) compare, center of gravity (N) forms at the downside place, therefore as in the exemplary embodiment in front, has likewise improved stability.
Though disclose the preferred embodiments of the present invention for schematic purpose, it will be understood by those skilled in the art that under the prerequisite that does not depart from scope of the present invention and spirit, various modifications, interpolation and alternative be possible.
