Herein, Fig. 2 is the position shown in the A of Fig. 1 by the amplified figure of the partial cross section of fluid balancer 30.Fluid is flat
Weighing apparatus 30 is the annulus for being sealed with liquid, is set as substantially concentric with roller 21, to rotate integrally with roller 21.It is flat in fluid
The inside of weighing apparatus 30 is equipped with innermost layer 31a, middle layer as the room for the inner space that can not be circulated with leaking out with liquid
This at least three layers of 31b, outermost layer 31c.Enclosed liquid, since the effectiveness in vibration suppression of the more big then fluid balancer 30 of specific gravity is bigger,
It therefore can be for example to be calculated as 50% suitable calcium chloride saturated aqueous solution or liquid below by the volumetric ratio of above-mentioned inner space
The liquid such as body metal or easy-to-handle water.In addition, fluid balancer 30 by by shell 32a and lid 32b rotating welding and with
It is sealed with the state engagement production of liquid.
As shown in Fig. 2, outermost layer 31c is set as inner space of the front end L2 than innermost layer 31a of its inner space
Front end L1 D1 rearward.In addition outermost layer 31c is set as inner space of the rear end L4 than innermost layer 31a of its inner space
Rear end L3 D2 rearward.That is, the whole installation of outermost layer 31c is rearward than innermost layer 31a, so as to form stepped part Ds.And
And outer cylinder 23 is equipped with corner portion 23e along stepped part Ds.It is vibrated as a result, in outer cylinder 23 and gap between cabinet 1 reduces
When, corner portion 23e becomes evacuation construction, and outer cylinder 23 and cabinet 1 interfere in order to prevent, and the diameter of roller 21 can be made bigger.That is, logical
The stepped part Ds being located in front of outermost layer 31c is crossed, while preventing outer cylinder 23 and cabinet 1 interferes, can be realized roller 21
The increase of major diameter, washing capacity.
In addition, in order to make built-in liquid stabilising, each layer of fluid balancer 30 is divided using baffle 33 in circumferencial direction
For multiple rooms.Baffle 33 is equipped with the opening portion 34 being connected between above-mentioned room.In addition, in the rotary shaft side Z of the opening portion of each layer 34
To front end or middle part, with rotary shaft Z generally vertical direction be equipped with slit portion 35.As a result, in 21 high speed rotation of roller
When built-in liquid being caused to concentrate on the peripheral side of the inner space of each layer due to centrifugal force, baffle 33 stops built-in liquid mobile
(a part of built-in liquid passes through in slit portion 35), therefore the adverse effects such as self-excited vibration can be inhibited.Meanwhile in roller 21
Revolving speed it is low to built-in liquid due to gravity be stored in lower section when, built-in liquid passes through in the big flow path of opening portion 34, because
This built-in liquid can smooth movement.In addition, inhibiting shell 32a when carrying out rotating welding to baffle 33 and covering the deformation of 32b, have
Workability improvement effect.
In present embodiment example, it is minimum for being set as the depth length h1 of the inner space of innermost layer 31a in layers.
The depth length h1 is distance of the front and rear end in rotary shaft Z-direction of above-mentioned inner space.That is, above-mentioned depth length h1 phase
Depth length h2 for the inner space of middle layer 31b is h1≤h2, and the depth of the inner space relative to outermost layer 31c
Length h3 is h1≤h3.The thickness d of the inner edge portion 30a of the depth length h1 dependent on innermost layer 31a can be made thinner as a result,.
Herein, Fig. 3 indicates the thickness d of the inner edge portion 30a of opening portion 21a and the relationship for preventing clothing from throwing away effect.It is first
First as shown in Fig. 3 (a), if increasing washing capacity, the amount of shared clothing increases in roller 21, therefore one of clothing sometimes
Divide and throws away from the opening portion 21a of roller 21 or the opening portion 23a of outer cylinder 23 to the outside of roller 21.If in a part of clothing
Rotate roller 21 in the state of throwing away, then as shown in Fig. 3 (b), the clothing of roller 21 since centrifugal force is extruded radially, because
This is pullled by the clothing in roller 21, and a part of the clothing thrown away is retracted the power F in roller 21 and is had an effect.Power F with
Revolving speed rise and increase, can be at a high speed therefore in the case where producing the power F for enough retracting the clothing being partially thrown out of
21 side of roller is retracted from the outer cylinder 23 of non-rotary body before dehydration.But clothing is thrown away in partially due to centrifugal force is extruded to
Edge part 30a, therefore since generated friction, hook, resistance R also have an effect when sliding on inner edge portion 30a.This
When, as shown in Fig. 3 (c), if the thickness d of inner edge portion 30a is thin, since centrifugal force makes clothing throw away portion extrusion inner edge
The range of edge 30a is small, and resistance R reduces, therefore is easy to throw away clothing and retracts in roller 21.Therefore, by make most helpful in
The depth length h1 for the innermost layer 31a for preventing clothing from throwing away is minimum in layers, even if washing capacity is big, also can more be prevented
Clothing carries out high speed dewatering under the state that throws away.
In addition in present embodiment example, the depth length h3 of the inner space of outermost layer 31c is maximum in layers.
That is, being h1≤h2≤h3 relationship.As a result, replace make the innermost layer 31a nearest apart from rotary shaft Z, centrifugal force is small it is above-mentioned into
Deep length h1 reduces, but the above-mentioned depth length h3 for the outermost layer 31c for keeping centrifugal force big increases, therefore it is flat to increase fluid
The whole effectiveness in vibration suppression of weighing apparatus 30.In addition, since there is new sky in the inner circumferential side of rear side and middle layer 30b in innermost layer 30a
Between, therefore also with the increased effect of volume of roller 21, the i.e. increased effect of washing capacity.
About above structure, illustrate its movement.It opens door 2 to put into washings in roller 21, and in lotion container 12
After putting into the lotion of predetermined amount, starts running, then washing procedure is first carried out.In washing procedure, water-supply valve 10b is opened and is supplied
The water given enters in outer cylinder 23 via lotion container 12 and water hose 10 together with lotion.The movement performs the predetermined time
Later, roller 21 is executed with the predetermined time and repeats the stirring action for rotating forward, stopping, reversing, stopping.At this point, being held in roller 21
The washings received iterates through the lifting rib 21b for being located at 21 internal perisporium of roller and is elevated in a rotational direction, from being elevated height
The stirring action that position falls is spent, therefore washings is carried out to clap washing.
After the movement has carried out the predetermined time, terminate washing procedure, executes dehydration procedure.It is first in the dehydration procedure
First drain valve 13b is opened, and the water in outer cylinder 23 is discharged to machine exterior via scupper hose 13.Then, roller 21 is revolved at a high speed
Turn (for example, 900r/min) and rotation set time, so that water contained by washings be made to be dehydrated.
After the dehydration procedure has carried out the predetermined time, water-supply valve 10b is opened to water supply, the water lotion container 12 with
And pass through in water hose 10, it is injected into outer cylinder 23, implements rinsing process.In the rinsing process, with above-mentioned washers
Sequence similarly, is executed with the predetermined time and repeats rotating forward, pause, reverses, the stirring action of pause movement.At this point, washings repeats
Be elevated in a rotational direction and being located at the lifting rib 21b of 21 internal perisporium of roller, from be elevated height and position fall stir
Movement is mixed, therefore lotion ingredient contained by washings is diluted, and is rinsed.In addition, having the drum washing of functions/drying
In the case where drying machine, drying process is being executed later.
As described above, making the depth length most helpful in the innermost layer 31a for preventing clothing from throwing away in present embodiment example
H1 is minimum, keeps the depth length h3 most helpful in the outermost layer 31c of the effectiveness in vibration suppression of fluid balancer 30 maximum, thus
Inhibit increased at a distance from the inner space back-end location L4 of the inner space front position L1 and outermost layer 31c of innermost layer 31a
Meanwhile can improve prevents clothing from throwing away effect and effectiveness in vibration suppression, therefore can take into account washing capacity and increase and low vibration.Meanwhile
It can make the inner space back-end location L4 distance D2 of the inner space back-end location L3 and outermost layer 31c of innermost layer 31a more
Greatly, therefore the volume of roller 21 increases, and can also obtain the increased effect of washing capacity.
In addition, described for tumbling-box washing machine in present embodiment example, the rolling for subsidiary functions/drying
Cartridge type scrubbing-and-drying unit can also obtain effect same.In addition, fluid balancer 30 includes 3 layers in present embodiment example, but in
Interbed 31b may be two layers or more.In addition, fluid balancer 30 in appearance be equipped with stepped part Ds, but even if for
The construction of multiple ladders can also obtain original purpose.In addition, not needed in the case where the gap of outer cylinder 23 and cabinet 1 is big
The corner portion 23e of outer cylinder 23, therefore inner space front end and L1 by making outermost layer 31c are almost the same, can also increase on
The depth length of inner space is stated, but does not change the size of L1 and L4, so as to obtain more preferably effectiveness in vibration suppression.
<embodiment 2>
Fig. 4 indicates the partial cross section of fluid balancer 40 in second embodiment example.It is same as Example 1, fluid balance
Device 40 is made by shell 42a and the engagement of lid 42b, includes at least innermost layer 41a, middle layer 41b, this three layers of outermost layer 41c
More than.Middle layer 41b can be two layers or more.In addition fluid balancer 40 is set as the in-built depth of innermost layer 41a
Length h1 is minimum in layers, and the depth length h2 of the inner space of middle layer 41b is maximum.That is, being h1≤h3≤h2
Relationship.In addition, the positional relationship of innermost layer 41a, outermost layer 41c, L1, L2, L3, L4 are same as Example 1.In addition, other
Structure and operating control are same as Example 1, mark the same symbol and omit the description.
According to above structure, effect similarly to Example 1 can be obtained, and needs to take the evacuation construction of stepped part Ds
Must be larger, even if also can at least increase effectiveness in vibration suppression in the case where the depth length h3 of outermost layer 41c cannot be increased and be greater than most
The depth length h2 of the middle layer 41b of internal layer 41a.That is, being not increase at a distance from L1 and L4 or L3 is at a distance from L4, just improve
The space-efficient of effectiveness in vibration suppression constructs.
In addition, it is same as Example 1, by reducing the depth length h1 of innermost layer 41a, the inner edge of opening portion 21a can be made
The thickness d of edge 40a is thin, therefore can also improve prevents clothing from throwing away effect.Also, also there is space in the rear side of innermost layer 41a,
Therefore the volume that can help to roller 21 increases.Therefore, even if being equipped with bigger stepped part Ds by the major diameterization of roller 21
In the case where, it can also obtain the effectiveness in vibration suppression of fluid balancer 40 and prevent clothing from throwing away effect, washing capacity increase can be taken into account
And vibration damping.
<embodiment 3>
Fig. 5 indicates the partial cross section of fluid balancer 50 in third embodiment example.It is identical as embodiment 1 and embodiment 2,
Fluid balancer 50 is made by shell 52a and the engagement of lid 52b, including innermost layer (first layer) 51a, second layer 51b, third
Layer 51c, the 4th layer of 51d, outermost layer (layer 5) 51e.In addition fluid balancer 50 is set as the inner space of innermost layer 51a
Depth length h1 is minimum in layers, and the depth length h3 of middle layer third layer 51c is maximum.That is, the depth of each layer is long
Degree is h1≤h2≤h5≤h4≤h3 relationship.
The following inner edge portion 50a for forming fluid balancer 50: by being located between innermost layer 51a and opening portion 21a
The diameter of bending section 57, opening portion 21a expands towards rear.The section of bending section 57 is about 90 degree of angle of fan, by it
Circular arc portion forms inner edge portion 50a.23 side of outer cylinder of bending section 57 be it is hollow, can be arranged for keep multiple ribs of intensity with
The counterweight of balance is obtained for the initial unbalance to roller 21.
In addition, being respectively equipped with bending section 58 and chamfering in the corner of the opening portion side 21a of innermost layer 51a and third layer 51c
Portion 59.That is, the corner of the stepped part Ds2 in 21 side of roller for being set to fluid balancer 50, the diameter direction equipped with opening portion 21a
The widened rake in rear.In addition, the inner space of each layer is again formed as depth along the rake for being set to the side opening portion 21a
Length increases towards peripheral side.In addition, rake may be provided in the corner of stepped part Ds.
Depth length h3 is maximum third layer 51c due to forming the next door 70a and 70b of inner space most in layers
It is long, thus in order to improve the workability of rotating welding, and plane 71a and 71b and plane 71c and 71d are formed, in crimping
Power is difficult to disappear.In addition, being equipped with baffle 53 in each layer, built-in liquid can pass through and circulate in opening portion 54 and slit portion 55.
In order to improve the workability of rotating welding, slit portion 55 is located at the side shell 52a.
Fluid balancer 50 is fixed on roller 21 using multiple bolts 56.Bolt 56 on rear side of outermost layer 51e due to wearing
It crosses, therefore the inner space of outermost layer 51a narrows at multiple positions.That is, outermost layer 51e is between the stepped part Ds in front and rear
Bolt 56 between.Therefore, the depth length h5 of outermost layer 51e is less than the layer (h5≤h3≤h4) than the inner side of bolt 56.
In addition, the positional relationship of innermost layer 51a, outermost layer 51c, L1, L2, L3, L4 are same as Example 1.In addition, other
Structure and operating control are same as Example 1, mark the same symbol and omit the description.
According to above structure, effect same as embodiment 1 or embodiment 2 can be obtained, and pass through bending section 57,58
And corner portion 59 forms the shape guided into roller 21, therefore more can prevent clothing from throwing away.This is because due to centrifugation
Power and be compressed in the clothing of bending section 57,58 and corner portion 59 and be easy to be pulled to roller 21 due to the component of centrifugal force
Side.In addition, built-in liquid is since centrifugal force concentrates on peripheral side, so even since above-mentioned rake causes inner space to become
Narrow, the influence to effectiveness in vibration suppression is also small.That is, the depth length of above-mentioned inner space towards periphery and increased shape can take into account it is anti-
Only clothing is thrown away and effectiveness in vibration suppression.
