Description

The home appliances with compacting pattern

The present invention relates to the home appliances of a kind of home appliances, especially a kind of water running.Especially, the present invention relates to the field of washed articles treater tool, described washed articles treater tool is for washing and/or dry washing material.

By the known home appliances with cabinet shape housing of WO2010/066653A1.This cabinet shape housing comprises a plurality of walls, and in described a plurality of walls, at least one wall has the layout of pressing part.The described layout of pressing part comprise about the center of this wall arrange, in top view ringwise the first pressing part, with respect to this first pressing part be arranged in one heart outside this first pressing part, in top view ringwise the second pressing part and the 3rd pressing part that arrange outside described the second pressing part, band shape.At washing machine and other, be provided with in the home appliances of parts of rotation especially, by this configuration, realize the effect that can reduce vibration and noise, because described vibration and noise pass to the correspondingly wall of configuration indistinctively, and not because the vibration of wall is strengthened.

But, in the home appliances known by WO2010/066653A1, see, for example, in when operation, in drying program, although there is the layout of pressing part, noise still can be awared.This relates to definite especially frequency range, although because the possible vibration mode of pressing part limiting wall may be created in the other vibration mode in audible frequency range.Here, the vibration mode of higher-order also may occur, described vibration mode also can the frequency range in hearing within certain limit in.So, for example, at run duration, while dry accelerating, replace inhomogeneous noise spectrum and produce by the noise spectrum of the arrangement constraints of pressing part.Especially, by the plate construction forced vibration node that causes of compacting in deformed region respectively, the also possible diaphragm of plate members is limited to several citation forms thus.

In this article, " paving " can be regarded as is arranged in surface or lip-deep structure, described structure consists of a large amount of single bin parts, and described bin part has any size that is no more than maximum length, and described maximum length is significantly less than each maximum gauge on described surface.Accordingly, described in the common examples of paving be the lining face for the floor in room, described lining face consists of bin part wooden or pottery, described bin part has any size of the size that is significantly less than the floor of considering accordingly.Common counter-example can be the lining face for such floor, and described lining face is comprised of solid wood or plank, and described solid wood or plank extend to opposite side from a side in room.The illustrated structure in starting the WO 2010/066653A1 mentioning of the wall of home appliances is not paved.

The United States Patent (USP) 4,133,152 of inventor Luo Jie Roger Penrose (Roger Penrose) has illustrated that the surface that element a kind of closure, acyclic, that " pave part " by means of a plurality of being known as carries out paves.Described surface can be the end of building or the developmental game of wall or picture mosaic class.Acyclic paving is like this called " Roger Penrose is paved " now widely.By WO 2001/085274A1, also learn such paving.

Task of the present invention is, proposes a kind of home appliances, and described home appliances has further improved structure.Especially, task of the present invention is, a kind of home appliances is described, noise decrease radiation in described home appliances.

This task solves by the home appliances corresponding to independent claims.By in dependent claims or the following description, explain or shown feature and measure in the accompanying drawings can advantageously expand according to home appliances of the present invention.

Therefore, described task can solve by being especially configured as the home appliances of the home appliances of water running, wherein, is provided with housing and described housing and has at least one with the housing wall of compacting pattern, and wherein, described compacting pattern is paved based on Roger Penrose.

Due to the compacting pattern of paving based on Roger Penrose, do not allow from the beginning symmetry.Thus, described compacting pattern is not only optionally to work for possible diaphragm, but works integrally to suppress the mode of vibration.This means, the intrinsic vibration not given in advance of described compacting pattern, described intrinsic vibration can cause the optimized frequency scope of vibration when operation.This relates to the intrinsic vibration of the wavelength in the order of magnitude of the mark (Bruchteilen) having in board size.Here, described mark for example, by the proportionate relationship of small integer, 1/2 or 2/3 obtain.

In an advantageous manner, Roger Penrose is paved by a plurality of parts of paving and is combined into.Here, also advantageously, compacting pattern has face piece, described piece respectively configuration at Roger Penrose, pave pave part within.Especially, this is favourable, and face piece is configured as smooth face piece.Simplify and manufacture thus.

Although when configuration compacting pattern, face piece itself has film surface, produces again the vibration mode of definite diaphragm on described film surface now on less yardstick.But the structural constant of compacting pattern can be correspondingly littlely given in advance, thereby such vibration has insignificant impact to sound emission with regard to its frequency and amplitude.Thus, with respect to the configuration of not suppressing of housing wall or the configuration of compacting periodically, can structure realize the remarkable reduction of sound emission.Meanwhile, with regard to realized effect, can realize cheaply the configuration of suppressing pattern by cost.Especially, in the comparable situation of manufacturing expense, can realize thus the significantly improved decay of diaphragm.

This is also favourable: compacting pattern has connection strap, and extend on the limit being bonded with each other of paving part that described connection strap is paved along Roger Penrose respectively.For example, face piece can be configured as in housing wall as recess between connection strap.Here, due to certain connection strap width, with respect to given in advance the paving for part size of paving part, the width of face piece reduces.In addition, form face piece geometry spacing relative to each other.In the situation that the size of paving part that Roger Penrose is paved and layout are given, this has realized further noise attentuation and/or improved Vision Design.

This is favourable equally: width or the mean breadth of the connection strap width of connection strap or average connection strap width specific surface piece are little.This is especially possible: connection strap forms that be associated, smooth face to a certain extent, and face piece is separated mutually by connection strap respectively.Less connection strap width by connection strap is avoided relevant therewith vibration mode.The connection strap of compacting pattern is here shaped in an advantageous manner between the face piece of compacting pattern.

For the size of the face piece of enough little compacting pattern given in advance with regard to the intrinsic frequency with regard to possible and for further restriction manufacturing expense, this is favourable: be combined into the scope of the quantity of paving part from 10 to 100 that Roger Penrose paves and select.Particularly advantageously, pave the scope of quantity from 20 to 80 of part and select.In addition it is favourable from 30 to 50 scopes of paving part, selecting.Especially, being combined into the quantity of paving part that Roger Penrose paves can be about 40.

Roger Penrose is paved and is preferably included two different part kinds of paving, described in pave the shape of part kind and rule that arrangement mode is paved by Roger Penrose is determined, to can realize quasi periodic generally.Show thus that aperiodicity paves part pattern, by described aperiodicity, pave part pattern and can seamlessly pave (being revealed as infinite expanding) plane, and at this, periodically do not repeat citation form (Grundschema).In actual enforcement, this paves the size that part pattern is limited to housing wall.Due to manufacturability and assembling capacity, for the compacting pattern of housing wall here also can be provided with around edge.In addition, can on the determination portion position of compacting pattern, suitable forming part be set, described forming part is for example because fixing assembling is in other words essential.

Here, Roger Penrose is paved the different modification that for example can realize due to the former of design thereby the form that can use.Also can consider, by compacting pattern, the shape of mating of the element of face piece and connection strap especially, also additionally reduce the remaining intrinsic vibration of these elements (structural detail).Where necessary, also can destroy partly one or more in composition rule, for example, due to the reason of process technology or in order to meet member symmetry given in advance.For example, housing wall can be combined into by two part sheet materials.Yet, preferably housing wall single type ground, especially by sheet material, manufactured.

Thus, this is favourable: Roger Penrose is paved and by first, paved part kind and second and pave part kind and be combined into, described first paves the rhombus of part kind based on having the angle of 36 ° and 144 °, and described second paves the rhombus of part kind based on having the angle of 72 ° and 108 °.This configuration can be realized shapely compacting pattern and can realize on the other hand effective vibration vibration damping on the one hand.Thus, can configuration to the visible housing wall of user.Especially, this is favourable: housing is configured as the housing of cabinet shape, and the first side wall of housing and the second sidewall have respectively compacting pattern, and described compacting pattern is paved based on Roger Penrose.Yet the front side of housing also can have the compacting pattern of paving based on Roger Penrose.The other sidewall of housing also can have respectively the compacting pattern of paving based on Roger Penrose.

Yet, in the configuration of housing, also can consider, the compacting pattern of housing wall is greater than two Roger Penroses of paving part kind and paves based on having.

Thus, except reducing sound emission, also can realize design new-type and original creation, described design shows remarkable visible different characteristic with respect to traditional home appliances.Also by compacting pattern, improve the stability of shell wall here.Therefore the compacting pattern of, paving based on Roger Penrose also can be used in the wall thickness that reduces shell wall.Saving that this has realized material.
