Summary of the invention
Problems to be solved by the invention
But the calibration capability of fluid balancer depends on the amount of liquid enclosed in inside.Thus, it is supposed that real radially
In the case where having showed slimming, in order to ensure identical internal volume, need to extend height.In general, when in order to carry out centrifugal dehydration
Draining, dehydration groove body side be formed with drainage hole.But if extending the height of fluid balancer, it is dehydrated slot master
The height of the side of body can correspondingly shorten, and the region that supply and discharge water hole is formed can narrow and dewatering is caused to decline.Therefore, no
The height of fluid balancer can unlimitedly be extended.In view of the purpose for inhibiting this fluid balancer of vibration original, cannot achieve
The miniaturization that internal volume by cutting down fluid balancer reaches.
In addition, dehydration slot diameter it is bigger or dehydration when revolving speed it is higher, then act on fluid balancer, dehydration slot from
Mental and physical efforts are bigger.Therefore, in order to make fluid balancer possess sufficient radial crushing strength, such as in the dehydration for making diameter 460mm
Under conditions of slot is operated with dehydrating speed 700rpm, the resin thickness by the gabarit of fluid balancer is needed to be set as 3mm
More than.
In addition, in the case where being reinforced using metal strengthening part balancer device, in order to by made of metal
Independent component be fixedly installed in resin will lead to manufacturing process complication, and manufacturing cost increase.In addition, strengthening part
Presence can correspondingly cut down the internal volume of balancer device, cut down amount of liquid enclosed inside it, thus cause to correct energy
Power decline.
The present invention provides a kind of dewaterer, can seek under the premise of not sacrificing the calibration capability of balancer device slim
Change, and seeks the expansion of the bore of the opening portion of swivelling chute.
Dewaterer of the invention includes: swivelling chute, to there is round-ended cylinder shape, has opening portion, in opening portion configured with circle
Cricoid balancer device；Outer groove can rotate packet in swivelling chute；Driving portion is configured at outer groove, for rotation
Slot is driven and makes its rotation；And isolation mounting, external groove carry out isolated supporting.In addition, in balancer device, benefit
Gabarit is formed with metal material, and the gabarit includes inner side surface and outer lateral side and cricoid upper surface and the bottom of cylindrical shape
Face is sealed with liquid in the inside of gabarit.
Using the structure, the intensity of the gabarit entirety of balancer device is improved, with the resin with same calibration capability
The balancer device of gabarit processed is compared, and balancer device can be made to minimize in the state of keeping intensity and constant internal volume.
In addition, the larger situation of the weight of balancer device itself is also effective to vibration is inhibited.Therefore, it is being higher than tree using specific gravity
The metal material of the specific gravity of rouge correspondingly improves the inhibitory effect of vibration come when forming gabarit, weight increases.The increase as a result,
The internal volume of amount compensator balancer device of weight cut down and amount of liquid is cut down, so as to realize balancer device into one
The miniaturization of step.
Dewaterer of the invention is the knot that balancer device can be made to minimize in the state of maintaining calibration capability constant
Structure, therefore high capacity can be realized under the premise of not enlarged.In addition, by being then able in the case where not making radial crushing strength
The structure for being thinned balancer device under the premise of drop, therefore the expansion of the bore of the opening portion of swivelling chute can be sought.
In addition, be set to dewaterer swivelling chute fluid balancer disequilibrium regulating ability depend on gabarit enclose
The weight of liquid.Therefore, for fluid balancer, in liquid biggish using specific gravity, even identical volume
It can be improved disequilibrium regulating ability.In addition, disequilibrium regulating ability if they are the same can if, then it is flat can to reduce fluid
The volume of weighing apparatus.If the volume of fluid balancer can be reduced, have the following advantages, that is, dewaterer main body can be reduced, or
The opening portion etc. of swivelling chute can be increased by the way that fluid balancer is thinned.
But for previous dewaterer, sodium-chloride water solution or calcium chloride water are accommodated in fluid balancer
Solution.The specific gravity of sodium-chloride water solution is up to 1.20 or so, and the specific gravity of calcium chloride is 1.35 or so.In the presence of with aqueous sodium chloride
The specific gravity of liquid or calcium chloride water reduces volume such problems of fluid balancer with being unable to fully.
In addition, there are limits in dissolubility for sodium chloride or calcium chloride, it is difficult to obtain the aqueous solution of high concentration.For example,
In the case where calcium chloride, if the aqueous solution of 40wt%, then it can not be completely dissolved at room temperature.Therefore, in fluid balancer
The raising of specific gravity of liquid there are the limit, the disequilibrium regulating ability of fluid balancer can not be improved.
In addition, using sodium-chloride water solution or calcium chloride water as fluid balancer internal flow the case where
Under, in excessive concentration, it is precipitated in the environment of low temperature.In production, in order to avoid density unevenness and undissolved powder
End remains in problem equal in fluid balancer, is actually mostly come with lower concentration using above-mentioned aqueous solution.Fluid is flat as a result,
The specific gravity of internal flow in weighing apparatus declines, and existing is more difficult to ensure disequilibrium regulating ability such problems and is more difficult to realize stream
Miniaturization such problems of body balancer.
In dewaterer of the invention, it is water-soluble that the liquid enclosed in the inside of the gabarit of balancer device is set as potassium carbonate
Liquid.
The specific gravity of wet chemical is up to 1.50 or so.Thus, for dewaterer of the invention, by will be
The enclosed liquid in the inside of the gabarit of balancer device is set as wet chemical, thus with used in the past sodium chloride, chlorination
Calcium phase ratio can further increase the disequilibrium regulating ability of balancer device.Thereby, it is possible to seek the small-sized of balancer device
Change.In addition, being capable of increasing the opening portion of swivelling chute to improve the convenience for being removed or placed into clothing etc. relative to swivelling chute.
For dewaterer of the invention, on the basis of having also contemplated the use environment of low temperature etc., it can be improved
The specific gravity of the enclosed liquid in the inside of the gabarit of balancer device.Thereby, it is possible in the shape for maintaining disequilibrium regulating ability constant
Reduce the volume of balancer device under state.Thus, it minimizes balancer device and improves environmental suitability, be capable of providing energy
Inhibit dehydration and vibration and environmental suitability also excellent dewaterer.

Greatly, it is tilted relative to the rotation axis of swivelling chute 34 towards outside on longitudinal section.Therefore, it will be pushed away under the influence of centrifugal force
The clothing of pressure guides downwards, prevents clothing from flying out from opening portion 43.Equally, also the water deviate from will be centrifuged from clothing and floating
It washes in process and is attached to the water etc. of the inner side surface S1 of balancer device 44 and guides downwards, fly them will not from opening portion 43
Out.
In addition, the tilt angle of inner side surface S1 is configured to two stages, by the changed connection of above-mentioned tilt angle
The position in portion 45 is set as putting into the upper surface location when clothing of maximum capacity.That is, the limit height of the clothing of storage is set
It is set to until interconnecting piece 45 of multiple inclined surface of the inner side surface S1 of balancer device 44.Therefore, shape can be utilized
The storage limit of clothing is shown in which position at a glance, user can be prevented accidentally excessively to be put into clothing.In addition,
In the case where being only compared with the balancer device of slimming 44, mark is arranged to improve clothing by the height in midway
The storage limit, increase swivelling chute 34 clothing storage amount.
In addition, being two stages by the angle initialization of inclined surface, but not limited to this in the present embodiment.That is,
Can be, the tilt angle relative to rotation axis of inner side surface S1 is configured to two more than the stage up and down, be formed as more to
Junior go then tilt angle it is bigger.The shape also includes the circular shape being smoothly formed.As a result, closer to balancer device 44
Then tilt angle is bigger for lower end, therefore the clothing for being easy to will push against in the inner side surface S1 of balancer device 44 draws downwards
It leads.
In addition it is also possible to which swivelling chute 34 is formed using stainless steel and other metal materials as present embodiment.It wraps as a result,

(the 6th embodiment)
Hereinafter, illustrating the dewaterer of the 6th embodiment of the invention.
The basic structure of the dewaterer of present embodiment and balancer device in a same manner as in the first embodiment, therefore is omitted each
The explanation of constituent element.
The dewaterer of present embodiment is characterized in that, the liquid enclosed in the inside of the gabarit of balancer device is set as
Wet chemical.
Fig. 8 is the figure for indicating the data for the liquid enclosed in the inside of the gabarit of the balancer device of present embodiment.?
In Fig. 8, in order to be compared, the data of the wet chemical of each concentration are shown and the calcium chloride water that uses in the past
Data.
For the dewaterer of present embodiment, it will be enclosed in the balancer shell of the gabarit as balancer device
The liquid in portion is set as the wet chemical of concentration 40wt%.The deliquescent limit of previous calcium chloride is lower, concentration
The calcium chloride water of 35wt% is the limit in practical application.The specific gravity of the wet chemical of concentration 40wt% is about
1.41, compared with the case where having used the calcium chloride water of concentration 35wt% that specific gravity is about 1.35, it can make as flat
The volume of the enclosed liquid in the inside of the balancer shell of the gabarit of weighing apparatus reduces about 4%.
As a result, for the balancer device of the dewaterer of present embodiment, can with comparably ensure in the past
The disequilibrium regulating ability of balancer device is reduced opposite with the volume with the liquid enclosed in the inside of gabarit under the conditions of this
The ratio answered is thinned the thickness radially of balancer device.Thus, it is possible to minimize balancer device.In addition, can
Keep the internal diameter i.e. opening diameter of opening portion of balancer device bigger than previous opening diameter.
In addition, the higher situation of concentration of potassium carbonate causes the specific gravity for the liquid enclosed in the inside of gabarit higher, balancing
The small volumeization of device device is effective on this point.The limit of previous calcium chloride water is 35wt%, in contrast, carbon
Sour aqueous solutions of potassium can improve concentration to 47wt% or so.But wet chemical be concentration 50wt% in the case where at
For substantially saturated dissolution, therefore can lead to the problem of in the case where the concentration of 50wt% or more in low temperature when, generates precipitating etc..
Thus, the wet chemical enclosed in the inside of gabarit is set as the balancer device of the dewaterer of present embodiment
Concentration 40wt% or so is more real, therefore preferably.
As shown in figure 8, in the case where more than concentration 35wt%, can obtain it is identical as the specific gravity of calcium chloride water or
The wet chemical of specific gravity above.
In addition, the wet chemical used in the present embodiment also has excellent characteristic in terms of frost resistance.?
In that column of frost resistance in table shown in Fig. 8, it will will not freeze with -13 DEG C of holdings and also not have in other respects assorted
The case where special problem, is expressed as zero.In the case where concentration 47wt%, locally freezed under -13 DEG C of environment, but
In concentration 45wt% situation below, any problem does not occur.
Moreover, needing to pay attention to overheat and supercooling for the liquid that the inside of the gabarit in balancer device is enclosed
The generation of phenomenon.
When superheating phenomenon occurs for the liquid in balancer device, liquid is the temperature of the fusing point become inherently or more
Degree will not melt but maintain frozen state.For example, the liquid when cold district uses dewaterer, in balancer device
It can freeze at night, then in the case where carrying out the dehydration of clothing after daytime temperature becomes fusing point or more, exist following hidden
Suffer from, that is, the liquid in balancer device is to maintain the state of frozen state.In this case, liquid is in balancer device
With the state freezing of concentration of local.It can be led to the problem of when becoming state as described above as follows, that is, not only can not be as balance
Device device functions, and instead can cause imbalance.
In addition, in the case that supercooling phenomenon occurs for the liquid in balancer device, even if confirming in operation start
Liquid in balancer device just starts the operating of dewaterer after not freezing, it is also possible to sharply frozen ground during operation
Knot.At that rate, the liquid in balancer device can freeze in a specific state and no longer flow.Becoming shape as described above
It can be led to the problem of when state as follows, that is, can not function as balancer and instead can cause imbalance.
For the balancer device of the dewaterer of present embodiment, using wet chemical as in gabarit
The enclosed liquid in inside, so that problem as described above will not occur in concentration 45wt% situation below.Thus, this implementation
The balancer device of the dewaterer of mode does not allow easy freezing, is able to maintain that for overheating the generation with supercooling phenomenon excellent yet
Different disequilibrium regulating ability.
In addition, the wet chemical used in the present embodiment also has excellent characteristic in terms of corrosivity.?
In that column of corrosivity in the table of Fig. 8, the test specimen of SUS430 is soaked in liquid, rust is precipitated in a liquid or generates precipitating
In the case where, be expressed as ×.In the case where calcium chloride water, rust was produced by 3 days or so, in contrast, in this reality
In the case where applying wet chemical used in mode, it have passed through 60 days or more also without generating rust.In this way, stainless steel will not
It is carbonated aqueous solutions of potassium corrosion.Thus, the balancer device of the dewaterer of present embodiment is able to use thin more stainless than previous
Steel can be realized miniaturization as the gabarit of balancer shell.
In addition, for the balancer device of the dewaterer of present embodiment, by constituting gabarit using stainless steel,
So as to prevent carbon dioxide from penetrating and enter inside balancer device.When carbon dioxide penetrates and enters in balancer device
When, there are following hidden danger, that is, such reaction shown in following chemical formula occurs, generates saleratus.
K2CO3+CO2+H2O→2KHCO3
The solubility of saleratus is lower than the solubility of potassium carbonate, therefore it may if the concentration of saleratus is higher
It is precipitated.When the liquid in balancer device is precipitated, there are following hidden danger, that is, when dewaterer carries out dehydration rotation,
Precipitate is centrifuged, and unevenly fixed so as to cause injustice in the balancer shell of the gabarit as balancer device
Weighing apparatus.
In the case where balancer shell is made of resin, from the metals such as stainless steel the case where is different, and carbon dioxide can be through flat
Weighing apparatus shell.Thus, the generation of saleratus in order to prevent needs that balancer shell is made to have sufficient thickness.In present embodiment
Balancer device in, by by constitute balancer shell component be set as the metals such as stainless steel, so as to make balancer shell 44a's
Material is relatively thin and realizes miniaturization.
