Description
Technical field
The present invention relates to washing machine field, particularly relate to a kind of Double-rotary drum washing machine.
Background technology
Washing machine be a kind of can the household electrical appliance of washing clothes, dryer be then a kind of can the household electrical appliance of drying clothes.In recent years, the washing-drying integral machine integrating laundry and clothes drying function also widely uses.Hereinafter, for ease of illustrating, by washing machine, dryer and integrate laundry and the washing-drying integral machine of functions/drying is referred to as washing machine.
Washing machine is generally divided into impeller-type and drum-type, and motor shaft and the washtub axle of pulsator washing machine are generally vertical setting, are top door opening; The motor shaft of drum-type and washtub axle are generally and are horizontally disposed with, and have top door opening and open front.Traditional roller washing machine generally adopts open front, is directly installed on ground and uses.Because the clothes inlet of washing machine is lower, user causes a lot of inconveniences clothing being put into washing machine and take out clothing from washing machine.
Generally, each family only has a washing machine, in order to wash dissimilar clothing, use or start washing machine several times.Such as, clothing may be divided into adult's clothing and underwear and children's clothing, in order to after washing both and the former, need use twice washing machine.Therefore, need expensive wash time and consume a lot of energy.And consider conserve energy, when washing a small amount of clothing, use leviathan of the prior art not to be preferred.The washing process arranged in leviathan generally consumes a large amount of water, and power consumption is also large.
Further, because the laundry amounts of washing process expection is comparatively large, so wash time is relatively long.In addition, leviathan is provided with washing process, and the mainly general clothing of expection, may be not suitable for washing meticulous clothing such as such as underwear or child clothes etc.And when often washing a small amount of clothing, leviathan is also inappropriate.Clothing is collected some skies or longer time to wash the clothing of suitably large useful load by consumer.Consider the factor of health aspect, it is unhelpful for underwear, children's clothing and similar articles being placed for a long time.If such clothing is placed for a long time, dirt will stick on clothing, cause the problem that dirt can not thoroughly be removed.
Therefore, be provided on the basis of traditional leviathan, the necessity of setting up the much smaller small washing machine of a capacity increases.But although be small-sized, consider space utilization situation, it is not preferred for arranging two washing machines in one family.In view of this, some patents propose technical scheme:
If application number is the Chinese patent of 200810109942.8, washing machine.The invention provides a kind of can washing or the washing machine of drying clothes.This washing machine comprises: the first washtub, its accommodating laundry; Housing, this first washtub is arranged in the predetermined space of this housing; Second washtub, it is arranged in this housing, in order to this first washtub accommodating laundry dividually; And supporting member, it, relative to this second washtub of this housings support, substantially stops the displacement of the second washtub caused due to the load of the second washtub, and the displacement of the vibration of the second washtub is limited in predetermined amplitude.But due to, in this technical scheme, two washtubs are not interconnected, and the excesssive gap between result in adds the volume of washing machine.And, due to existing Double-rotary drum washing machine, be all that the first washtub is connected the damping of a set of independent setting respectively with the second washtub, this not only adds part of washing machine quantity, also add the volume and weight of washing machine.
In view of this, special proposition the present invention.
Summary of the invention
The object of the present invention is to provide a kind of Double-rotary drum washing machine, for realizing goal of the invention, adopting following technical scheme:
A kind of Double-rotary drum washing machine, comprising: be arranged on the first urceolus in washing machine frame and the second urceolus; The first described urceolus is connected through connector with the second urceolus, to be integrally formed structure; The first urceolus be connected is connected with framework with the damping device of the second urceolus through sharing.
Further, described damping device comprises, the first damping device that first urceolus is connected with framework, the second damping device that the second urceolus is connected with framework, and the 3rd damping device that the first urceolus or the second urceolus are connected with the middle cross beam that framework is arranged.
Further, the first described damping device is the extension spring that the first urceolus top is connected, and described extension spring is connected with framework; The second described damping device is at least one damper that the second urceolus bottom is connected, and described damper is connected with framework.
Further, the 3rd described damping device is the extension spring that the second urceolus top is connected, and described extension spring is connected with framework middle cross beam.
