Abstract
The utility model relates to a rear barrel structure capable of reducing noise and a rolling washing machine with same. The utility model has the technical scheme that the rear barrel structure of the rolling washing machine is characterized in that abnormal noise caused by the rear barrel structure when an inner barrel rotates at a high speed is reduced through reducing and/or lowering the number and/or the height of reinforcing ribs on the front surface of the bottom of a rear barrel. Preferably, the rear barrel structure of the rolling washing machine is characterized in that the reinforcing ribs are not arranged on the front surface of the bottom of the rear barrel. More preferably, the front surface of the bottom of the rear barrel is a smooth plane structure. Most preferably, the reinforcing ribs are arranged at the back surface of the bottom of the rear barrel. In order to ensure the strength of the whole barrel at a reverse position after the rear barrel structure is adopted, a plurality of reinforcing ribs can be increased at the back surface of the bottom of the rear barrel.
Description
Technical field
The utility model relates to tumbling-box washing machine, particularly a kind of back barrel structure of improved roller washing machine and have the roller washing machine that improves the back barrel structure.
Background technology
The roller washing machine tub assembly is divided into interior bucket, outer bucket, and outer bucket is divided into preceding bucket, back bucket again, in the design process of back bucket, in order to strengthen intensity, often the bucket bucket end, back is designed to uneven muscle structure, and the degree of depth is 50mm.Particularly 6kg, 7kg roller washing machine when laundry machine dehydration is worked in tub assembly rotating with the 1400Rpm rotating speed because the existence of the resistance of wind, the back bucket of concavo-convex bucket bottom structure produces unusual whirlpool noise under inner core rotates at a high speed.At present 6kg washing machine noise can only reach B grade even inferior grade more about 64Db, for the following standard of A class 6 2Db some gap also, is necessary to improve the noise quality.
The utility model content
The purpose of this utility model be by a kind of new back barrel structure is provided and contain this washing machine that improves the back barrel structure be reduced in the abnormal sound that causes because of the back barrel structure when rotating at a high speed of bucket.
The technical solution adopted in the utility model is that the back barrel structure of roller washing machine is characterized in that: the quantity of the reinforcement in bucket bucket front, the end, back reduces and/or highly reduces.
Preferably, the back barrel structure of described roller washing machine is characterized in that: the front at the bucket end of described back bucket is not provided with reinforcement.
More preferably, the back barrel structure of described roller washing machine is characterized in that: the front at the bucket end of described back bucket is smooth planar structure.
Further, the back barrel structure of described arbitrary roller washing machine is characterized in that: the back side at the bucket end of described back bucket is provided with reinforcement.In order to guarantee to adopt behind the utility model the reverse position intensity of whole bucket behind the barrel structure, can increase many reinforcements at the back side at the bucket bucket end, back and guarantee reverse position intensity.
Adopt back of the present utility model barrel structure, can be reduced in effectively and reduce the noise that wind resistance produces under the inner tank of washing machine rotation situation at a high speed effectively.Can select the quantity and/or the height of the reinforcement in bucket bucket front, the end, back according to the performance indications that the washing machine needs reach.
Particularly when bucket bucket front, the end, back is not provided with reinforcement, the noise that has reduced the wind resistance generation under inner tank of washing machine rotation situation at a high speed effectively reaches noise A grade, tub assembly rotates with the 1400Rpm rotating speed in during laundry machine dehydration work, and this structure effectively reduces noise after tested.More preferably, when bucket bucket front, the end, back was not provided with the smooth flat of reinforcement, anti-acoustic capability was more outstanding, and noise reaches the 61Db acoustical power, effectively reduces noise 3Db acoustical power at least, and the noise of generation reaches noise A grade.
Further, in order to guarantee to adopt behind the utility model the reverse position intensity of whole bucket behind the barrel structure, can increase many reinforcements at the back side at the bucket bucket end, back and guarantee reverse position intensity.
The purpose of this utility model, advantage and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain.These embodiment only are the prominent examples of using technical solutions of the utility model, and all technical schemes of taking to be equal to replacement or equivalent transformation and forming all drop within the claimed scope of the utility model.

Specific embodiment
Noise test experiments method:
With CEWR-0008C noise test specification is benchmark, after the final RPM of dehydration stroke arrives 20 seconds, measure → 3 times maximum/set (1 time value be same test portion before about mean value) estimate that the dehydration noise of barrel structure washing machine compares behind existing back barrel structure washing machine and the utility model.
As follows by the roller washing machine 6A classification standard that heating is arranged:
Test result:
Existing back barrel structure washing machine: bucket bucket front, the end, back often is provided with a lot of reinforcements, and the concavo-convex degree of depth of reinforcement is 50mm, after tested, under inner tank of washing machine rotation situation at a high speed, the minimum 64Db acoustical power that reaches of noise.
Barrel structure washing machine 1 behind the utility model: when after a bucket bucket front, the end reinforcement is not set, when back bucket bucket bottom back side is provided with reinforcement, under inner tank of washing machine rotation situation at a high speed, tub assembly rotates with the 1400Rpm rotating speed in during laundry machine dehydration work, effectively reduce noise after tested, the noise that has reduced the wind resistance generation effectively reaches noise A grade.
Barrel structure washing machine 1 is when the smooth flat of reinforcement is not set when the bucket bucket end, back is positive behind the utility model, when back bucket bucket bottom back side is provided with reinforcement, anti-acoustic capability is more outstanding, tub assembly rotates with the 1400Rpm rotating speed in during laundry machine dehydration work, this structureborne noise reaches the 61Db acoustical power after tested, effectively reduce noise 3Db at least, the noise that has reduced the wind resistance generation effectively reaches noise A grade.
Therefore, back of the present utility model barrel structure, tub assembly rotates with the 1400Rpm rotating speed in when laundry machine dehydration is worked, with backward the bucket not flat structure under inner core rotates at a high speed, produce unusual whirlpool noise, new construction is optimized for bucket bucket front, the end, back and is designed to smooth surface, reinforcement is set overleaf, has both reduced the resistance of wind effectively, guaranteed reverse position intensity again.Effectively reduce noise after tested, and do not have influence cleaning other indexs such as rate and water consumption.
