Description
Technical field
The present invention relates to a kind of tumbling-box washing machine, this tumbling-box washing machine possesses collecting washings and the cylinder that can rotate, and carries out the cleaning of washings, rinsing and dehydration in this cylinder.
Background technology
Generally there is following situation: have level or inclination rotating shaft tumbling-box washing machine dehydration procedure in, washings is uneven state and unbalance state in cylinder.For this reason, in dehydration, sometimes the power of deflection applied to rotating shaft and produce vibration.The rotating speed of the amplitude of vibration and the cylinder of rotation square proportional.Sometimes following problem is produced: tumbling-box washing machine itself moves and noise can not operate etc. with the rotating speed more than rotating speed of a certain regulation strongly due to this vibration.
In order to alleviate by the unbalance vibration caused of washings, in tumbling-box washing machine in Japan, application employs the fluid balancer of liquid widely.Fluid balancer is the path arranging hollow tube annularly in the end perimembranous of the side, opening portion for putting into washings in cylinder and obtain.For fluid balancer, enclose the water about the half of path, or the salt solution about the half having considered anti-freeze and enclosed path.When cylinder High Rotation Speed when rotation () such as more than 900rpm, for the eccentric load due to washings produce unbalance, the liquid of fluid balancer automatically moves to position in opposite directions, unbalance position.This make use of the Mechanics Phenomenon as natural principle.
On the other hand, in recent years, as new balancer, a kind of ball balancer (such as with reference to patent document 1) using metal ball (being called ball afterwards) is proposed.Ball balancer is being installed on the inner circumferential of cylinder and possessing in the chamber being formed as the tubular container of ring-type along the mobile multiple balls freely of direction of rotation (circumferencial direction).Further, ball balancer is enclosed and is had the viscous liquids such as the silicone oil of the viscosity of regulation in identical chamber.Thus, the friction of ball and chamber is limited.In the same manner as fluid balancer, unbalance for what produce due to eccentric load, this ball balancer also automatically moves to position in opposite directions, unbalance position.Thus, absorb unbalance.
At this, the superiority of ball balancer relative to fluid balancer is described.The large difference of ball balancer and fluid balancer is the ball being contained in chamber interior.Compared with liquid, the proportion of ball is obviously large, even if accommodated identical volume in chamber interior, is also ball weight.That is, when the dehydration of cylinder High Rotation Speed, the unbalance maximum amount of suppression of ball is larger than the unbalance maximum amount of suppression of liquid.Thus, employ the cylinder of ball balancer compared with the cylinder employing fluid balancer, even if cloth deflection during dehydration is large, unbalance inhibition is also high.
In addition, known single ball balancer and dual ball balancer, wherein, this single ball balancer only configures ball balancer in the end perimembranous of the side, opening portion putting into washings in cylinder, the end perimembranous of this dual ball balancer in the side, opening portion of cylinder and these two positions configuration ball balancers of end perimembranous of bottom surface side.The tumbling-box washing machine employing ball balancer is nearly all dual ball balancer.Single ball balancer and dual ball balancer are identical in principle.That is, no matter which kind of ball balancer is all change the position of multiple ball when dewatering accordingly with the unbalance amount moment of time dependent washings, automatically revises unbalance (such as reference patent document 2).
In the past, when dual ball balancer, configure identical ball balancer (with reference to patent document 2) at two places at cylinder two ends.In addition, as the rotating shaft also idler pulley be firmly fixed at base plate via bearing of the motor of drive division.
In the structure shown here, to unbalancely comparing of producing when identical washings such as bath towel is placed near cylinder bottom surface with wetting state and when being placed near cylinder opening portion.Due to the change in location of the washings that only makes placement identical, therefore think that produced eccentric load is identical in theory, the Oscillation Amplitude rocked by the unbalance cylinder caused is all identical in the optional position of cylinder.But, in fact, even if there is identical cloth deflection, when the generation position of cloth deflection is near cylinder opening portion, the Oscillation Amplitude of cylinder is large, when the generation position of cloth deflection is near cylinder bottom surface, because the rotating shaft being directly connected in bottom surface absorbs a part for vibration, therefore the Oscillation Amplitude of cylinder is little.When simply identical ball balancer being configured at cylinder two ends, be particularly installed on the ball balancer of bottom surface side, Oscillation Amplitude little comparison produced with bottom surface side and restraint is superfluous.Therefore, dewater start time, the time of stopping causes not for suppressing the phenomenon collided with each other between unbalance ball.Consequent metallic sound becomes new noise problem.
For this situation, also proposed a kind of ball balancer by the side, opening portion of cylinder and keep intact and only the ball balancer of bottom surface side replaced with the novel balancer of fluid balancer.But, there is following problem: because the Oscillation Amplitude of cylinder is large, therefore produce abnormal vibrations, roller washing machine often stops.
When fluid balancer, starting from cylinder to rotate till reaching High Rotation Speed during (when starting to rotate hereinafter referred to as cylinder) and cylinder low speed rotation time, the liquid formed in the path of fluid balancer does not rest on a place, but is roughly evenly dispersed in whole path.Therefore, the eccentric load produced by balancer self is less than the eccentric load of washings.Thus, can think, when using fluid balancer, it is unbalance identical that overall unbalance size and the eccentric load by washings cause.
On the other hand, when ball balancer, when cylinder starts to rotate and cylinder low speed rotation time, form ball balancer tubular container chamber in rolling element (multiple ball) have the tendency focusing on a place.Thus, the eccentric load produced by ball balancer self is equal to, or greater than the eccentric load of washings.Therefore, when using ball balancer, overall unbalance size becomes the unbalance total size of the unbalance and ball balancer self caused by the eccentric load of washings.
In addition, when cylinder starts to rotate, when the position that the circumferencial direction of unbalance cylinder occurs ball balancer self is in position relationship in opposite directions relative to the position of the circumferencial direction that the unbalance cylinder caused by the eccentric load of washings occurs, that offsets each other is unbalance.At this, although there is the situation that overall unbalance size diminishes due to total, on the contrary, when occurred these two unbalance generation positions are same position, the Oscillation Amplitude rocked based on cylinder due to total increases.Thus, due to abnormal vibrations, tumbling-box washing machine stops or tumbling-box washing machine breaks down.In a word, basic reason is that ball balancer self produces large unbalance when cylinder starts to rotate.

Detailed description of the invention
Below, reference accompanying drawing is while be described embodiments of the present invention.In addition, the present invention is not limited to these embodiments.
(embodiment 1)
Fig. 1 is the side sectional view of the tumbling-box washing machine 51 of embodiments of the present invention 1.The tank 52 of bottomed cylindrical is contained in the inner side of tumbling-box washing machine 51.The inside of tank 52 contains the cylinder 53 of bottomed cylindrical.In the face side (being left side on Fig. 1) of the input washings of tumbling-box washing machine 51, opening and closing mode is freely provided with door 57.At cylinder 53 the tank opening portion 52a being provided with tank 52 and the cylinder opening portion 53a be communicated with in cylinder 53.Cylinder 53 has at cylinder bottom surface 53b and carries out rotationally supported rotating shaft 35 to cylinder 53.Cylinder 53 configures obliquely in the mode of bottom surface side lower than face side.Tank 52 also configures obliquely along cylinder 53.Tilt cylinder opening portion 53a is configured to towards oblique upper by making cylinder 53.Thus, user need not adopt the posture of significantly bending over just can take out washings in cylinder 53.In addition, compared with configuring the situation of cylinder 53 in the horizontal direction, the water be fed in tank 52 accumulates in rear side, even if also can obtain dark water storage state with few water yield.That is, even few water yield is also easy to make washings moisture.Tank 52 is suspended by being arranged at the spring 10 on top, is flexibly supported by being arranged at the shock absorber 55 of bottom.In addition, although the taking-up difficulty of washings and output reduce, cylinder 53 also can be level.
The seal (not shown) of tubulose is installed at the edge of opening of tank opening portion 52a.The front-surface side of seal is used for abutting airtight between door 57 and tank opening portion 52a with the rear side of door 57.Even if vertically and horizontally and the tank opening portion 52a of the tank 52 rocked back and forth move, also due to seal deform after the seal that can maintain between door 57 and tank opening portion 52a by pressure gate 57 rear side.In the outer lower portion of tank 52, the drive division that motor 54 is used as carrying out cylinder 53 rotary actuation is installed.The rotation of motor 54 is passed to the drum pulley 24 of the rotating shaft 35 being arranged at cylinder 53 via belt 23.Thus, by the rotation of motor 54, rotary actuation is carried out to cylinder 53.
The inside of cylinder 53 be provided with washings 13 can be lifted after make it fall protruding body 16.The washings lifted by protruding body 16 by carrying out rotary actuation to cylinder 53 clashes into the water surface etc. from the top of cylinder 53, washes by beating and is cleaned.Further, cylinder 53 is provided with multiple open-work 15.Can via open-work 15 from tank 52 to water flowing and ventilation in cylinder 53.
The face side bottom of tumbling-box washing machine 51 is provided with control part 56, and this control part 56 controls motor 54 etc. and controls the operations such as cleaning, rinsing and dehydration.Control part 56 possesses can with timer to the system that manages of whole controls of control of the various sensor such as drived control and level sensor (not shown) comprising feed water valve 11, draining pump 19, motor 54.
Fig. 2 is the stereogram of the cylinder 53 of the tumbling-box washing machine 51 of embodiments of the present invention 1.Fig. 2 illustrates the state that the rotation of cylinder 53 stops.In tumbling-box washing machine 51, rotating shaft 35 level of cylinder 53 or inclination.Thus, the state of the bottom deflection to the 53b side, cylinder bottom surface in cylinder 53 is become by the washings 13 of accommodating.When cylinder 53 rotates at high speed, washings 13 rotates with deflected condition.Therefore, large vibration is produced in this state.In order to suppress this vibration, need the balancer being used for averaging out with washings 13.
In fig. 2, near the cylinder end perimembranous of 53a side, cylinder opening portion, ball balancer 30 (the first balancer) is provided with.Fluid balancer 31 (the second balancer) is provided with near the cylinder end perimembranous of 53b side, cylinder bottom surface.These balancers contain weight in the inside of the tubular container 17 that hollow tubular obtains circlewise.Ball balancer 30 (the first balancer) contains the ball 58 of the metal spheroid as rolling element as weight in the inside of tubular container 17a.The liquid 32 of fluid balancer 31 (the second balancer) about the inside of tubular container 17b to be sealed with the half of tubular container 17b as weight.About this liquid 32, use common water, or consider the anti-freeze in winter and use salt solution etc.
Fig. 3 is the figure of the structure of the ball balancer 30 (the first balancer) of the tumbling-box washing machine 51 representing embodiments of the present invention 1.Ball balancer 30 (the first balancer) part basic compared with ball balancer in the past does not change.Ball balancer 30 (the first balancer) have be configured at 53a side, cylinder opening portion tubular container 17a, can the ball 58 of movement in tubular container 17a and viscous liquid 18.The axis that tubular container 17a is configured to axis and cylinder 53 is consistent with each other.Viscous liquid 18 is silicone oil etc., controls the movement of ball 58.In addition, even the sticking liquid of other tool, as long as identical effect can be obtained, silicone oil is not limited to.
As shown in Figure 2, under the state that cylinder 53 stops, washings 13 has the tendency of the bottom being positioned at 53b side, cylinder bottom surface.The liquid 32 being in the inside of the tubular container 17b forming fluid balancer 31 (the second balancer) accumulates in bottom.Further, the multiple balls 58 being in the inside of the tubular container 17a of ball balancer 30 (the first balancer) also focus on bottom.In addition, do not have to record the viscous liquid 18 being in the inside of tubular container 17a in this Fig. 2, but there is appropriate viscous liquid all the time between multiple ball 58 and tubular container 17a.
Use Figure 11 that the tumbling-box washing machine of comparative example is described.Figure 11 is the stereogram of the cylinder of the tumbling-box washing machine of comparative example.Figure 11 illustrates and rotates ball balancer 30 (the first balancer) when starting and the state of fluid balancer 31 (the second balancer).Figure 11 represents that cylinder 53 is in the ball 58 of the inside of tubular container 17a, is in the figure of the water movement of the inside of tubular container 17b when starting to rotate, and has the inscape identical with Fig. 2.If use this structure, then by arranging ball balancer 30 (the first balancer) near the cylinder opening portion 53a that the Oscillation Amplitude of the cylinder 53 caused in the deflection by washings 13 is large, play high unbalance inhibition.On the other hand, corresponding unbalance inhibition is played in the 53b side, cylinder bottom surface that the Oscillation Amplitude of cylinder 53 is little by arranging fluid balancer 31 (the second balancer).In addition, do not configure ball balancer in 53b side, cylinder bottom surface, therefore also can not produce the noise of 53b side, cylinder bottom surface.
In fig. 11, when using as washings 13 a bath towel with wetting state put into cylinder 53 inner and start dehydration, produce the eccentric load caused by the cloth deflection of washings 13, occur unbalance.Think all identical in any position of cylinder 53 by the Oscillation Amplitude rocked of the eccentrically loaded unbalance cylinder caused.But in fact near the 53b of cylinder bottom surface, the rotating shaft 35 being directly connected in bottom surface absorbs a part for vibration, and therefore Oscillation Amplitude is little, and near the 53a of cylinder opening portion, Oscillation Amplitude is large.In the figure, for ease of understanding, be unbalancely expressed as the arrow 40 being positioned at cylinder opening portion 53a by what caused by washings 13.
Fluid balancer 31 (the second balancer) when starting to rotate about cylinder 53, when particularly revolution is the low speed rotation of 80rpm ~ 100rpm and ball balancer 30 (the first balancer), be described the unbalance size produced by respective eccentric load.First, about fluid balancer 31 (the second balancer), the water being in the inside of the tubular container 17b forming fluid balancer 31 (the second balancer) disperses along the inner circumferential of tubular container 17b roughly equably due to centrifugal force.That is, the unbalance size produced by the eccentric load of fluid balancer 31 (the second balancer) self is less than the unbalance size of washings 13, therefore also can think not unbalance.
On the other hand, about the multiple balls 58 in the tubular container 17a of ball balancer 30 (the first balancer), the liquid 32 such as the weight ratio water of ball 58 self are heavy, tubular container 17a inside has been put into the viscous liquid 18 with certain viscosity, thus existed between ball 58 and tubular container 17a and rub.Based on this, when ball balancer 30 (the first balancer), when cylinder 53 low speed rotation, even if apply centrifugal force to a certain degree, also there is the tendency that ball 58 is concentrated to the place near the centre bottom and between the top of roll circumference as shown in Figure 11.The unbalance size that eccentric load by ball balancer 30 (the first balancer) self produces is shown as the size of arrow 41.The unbalance size that also there is this ball balancer 30 (the first balancer) self is equal to, or greater than the eccentrically loaded situation of washings 13.
Like this, the unbalance size being provided with the entirety of the 53a side, cylinder opening portion of ball balancer 30 (the first balancer) is the total size of the unbalance size of unbalance size and the ball balancer 30 (the first balancer) self caused by the eccentric load of washings 13.If supplemented in this said total size, then the unbalance position produced by the eccentric load of washings 13 is not fixed.When cylinder 53 starts to rotate, when the position that unbalance cylinder 53 periphery of ball balancer 30 (the first balancer) self occurs is in position relationship in opposite directions relative to the position of unbalance cylinder 53 periphery occurring to be caused by the eccentric load of washings 13, that offsets each other is unbalance.Thus, there is the situation that overall unbalance size diminishes due to unbalance addition.On the contrary, when produced these two unbalance generation positions are positioned at roughly the same position as shown in figure 11, overall unbalance size is arrow 40 and the total size of arrow 41.Thus, increased by the Oscillation Amplitude rocking generation of cylinder 53 and abnormal vibrations occurs.In addition, if rock large, then the performance of the equilibrium function of ball balancer 30 (the first balancer) becomes slower, thus can not carry out the transformation of the High Rotation Speed to cylinder 53 rapidly.
Below, again with reference to accompanying drawing, embodiments of the present invention 1 are described.Fig. 4 is the stereogram of the cylinder 53 of the tumbling-box washing machine 51 of embodiments of the present invention 1.Fig. 4 illustrates and rotates ball balancer 30 (the first balancer) when starting and the state of fluid balancer 31 (the second balancer).
In the same manner as comparative example, when using when putting into drums inside as a bath towel of washings 13 with wetting state and start dehydration procedure, occur unbalance due to the eccentric load caused by the cloth deflection of washings 13.The size that this is unbalance is arrow 40, does not change.Differ widely with comparative example, by utilize control part 56 change cylinder 53 rotation control do one's utmost eliminate by the eccentric load of ball balancer 30 (the first balancer) self produce unbalance.
Specifically, cylinder 53 from starting to rotate till reaching High Rotation Speed during rotation start time, control part 56 makes cylinder 53 rotate along identical direction to carry out acceleration and deceleration by a small margin.Such as repeatedly carry out the set action of 4 times (amounting to 8 times) " rotate 3 seconds with 120rpm, rotate 5 seconds with 90rpm ".Controlled by this rotation, multiple balls 58 initial set in the tubular container 17a of ball balancer 30 (the first balancer) is to a place, separated from one another gradually.Disperse in whole tubular container 17a rapidly as shown in Figure 4.Like this, the unbalance size produced by the eccentric load of ball balancer 30 (the first balancer) self is less than the unbalance size of washings 13, therefore also can think not unbalance.
In addition, about combination and the number of repetition of revolution during acceleration and deceleration, time, revolution, due to exist the shape of cylinder, the weight of ball and quantity, viscous liquid state until dispersion time and other various key element, therefore can not determine entirely.But, as long as the upper limit being set to the high regulation revolution of above-mentioned 120rpm makes the inapparent degree of lower vibration such as resonance revolution, such as, be about 150rpm.In addition, as long as the lower limit being set to the low regulation revolution of above-mentioned 90rpm makes the clothing of drums inside can not fall because centrifugal force is not enough, such as, be about 80rpm.The difference of these regulation revolutions is 15rpm.In addition, different revolutions can also be added.The time maintaining regulation revolution is about 0 second (consecutive variations) ~ 10 second and the acceleration and deceleration carrying out amounting to 2 times ~ about 15 times are by a small margin effective.Expressly setting does not need repeatedly to set after amounting to the acceleration and deceleration of 2 times to about 15 times.
As mentioned above, the tumbling-box washing machine 51 of present embodiment possesses: bottomed cylindrical cylinder 53, and it is supported in rotatable mode by the rotating shaft 35 of level or inclination, has the cylinder opening portion 53a for dropping into washings 13; And tank 52, it accommodates cylinder 53.In addition, possess: drive division 54, it carries out rotary actuation to cylinder 53; And first balancer, it is arranged near the cylinder end perimembranous of 53a side, cylinder opening portion, and this first balancer is that the first weight 58 is accommodated in the inside of the first tubular container 17a obtained circlewise at the first hollow tubular.In addition, possess: the second balancer, it is arranged near the cylinder end perimembranous with the opposition side of cylinder opening portion 53a, and this second balancer is that the second weight 32 is accommodated in the inside of the second tubular container 17b obtained circlewise at the second hollow tubular; And control part 56, it controls drive division 54.The first balancer and at least one party contained in the second balancer of the second weight 32 that contain the first weight 58 are the ball balancers 30 containing mobile multiple rolling elements 58 freely.Control part 56 is configured to make cylinder 53 rotate while carry out acceleration and deceleration along identical direction when cylinder 53 starts to rotate.
According to such structure, cylinder 53 from starting to rotate till reaching High Rotation Speed during rotation start time, control part 56 makes cylinder 53 rotate along identical direction to carry out acceleration and deceleration by a small margin.Thus, the multiple balls 58 focusing on a place formed in the tubular container 17a of ball balancer 30 (the first balancer) are separated from one another, and disperse rapidly in whole tubular container 17a.By suppress like this by the eccentric load of ball balancer 30 (the first balancer) self produce unbalance, the unbalance of the entirety of cylinder can be alleviated and reduce vibration and noise.And, cylinder 53 can be made to change to High Rotation Speed rapidly.Thus, the duration of runs, economize on electricity (contributing to energy-conservation) can be shortened.
In addition, tumbling-box washing machine 51, first weight about present embodiment is mobile multiple rolling elements 58, first balancer is freely ball balancer 30, and the second weight is liquid 32, and the second balancer is fluid balancer 31.Thus, by suppress by the eccentric load of ball balancer 30 (the first balancer) self produces unbalance, the unbalance of the entirety of cylinder can be alleviated and reduce vibrate and noise.
In addition, control part 56 carries out the acceleration and deceleration of cylinder 53 repeatedly when cylinder 53 starts to rotate, and makes liquid 32 in the inner dispersion of the hollow tube of fluid balancer 31 (the second balancer) thus.Thus, the unbalance size produced by the eccentric load of fluid balancer 31 (the second balancer) self is less than the unbalance size of washings 13, therefore also can think not unbalance.
In addition, rolling element comprises metal ball.Thus, the proportion of metal ball is obviously greater than the proportion of liquid, even if accommodated identical volume in the inside of tubular container, also due to metal ball weight, therefore, when cylinder carries out the dehydration of High Rotation Speed, the unbalance maximum amount of suppression of metal ball is greater than the unbalance maximum amount of suppression of liquid.
In addition, in ball balancer 30 (the first balancer), be filled with the liquid 18 of the viscosity with regulation.Thereby, it is possible to control the movement of ball 58.
(embodiment 2)
Then, the tumbling-box washing machine 61 of embodiments of the present invention 2 is described.Fig. 5 is the side sectional view of the tumbling-box washing machine 61 of embodiments of the present invention 2.In the inscape of tumbling-box washing machine 61, the inscape identical with the inscape of the tumbling-box washing machine 51 of embodiment 1 uses the Reference numeral identical with the Reference numeral of embodiment 1, and the description thereof will be omitted.
Fig. 6 is the stereogram of the cylinder 53 of the tumbling-box washing machine 61 of embodiments of the present invention 2.Fig. 6 illustrates the state rotating and stop.
In present embodiment 2, near the cylinder end perimembranous of 53a side, cylinder opening portion, be provided with ball balancer 30 (the first balancer).Ball balancer 62 (the second balancer) is provided with near the cylinder end perimembranous of 53b side, cylinder bottom surface.As described below, these two ball balancers except the shape of tubular container is different, the number of ball, size and weight is slightly except difference, roughly has identical function.
In addition, ball balancer 30 (the first balancer) is respectively 7 and 4 with the number not being both the ball 58,63 of accommodating in respective tubular container 17,33 of ball balancer 62 (the second balancer).In addition, the size of ball 63 is slightly little, and weight is also slightly light.Tubular container 17 is different with the shaped slightly of 33 thereupon, or the amount of viscous liquid 18 is slightly different, or the viscosity of viscous liquid 18 is different.But, roughly the same as the basic function of balancer.
Below, reference accompanying drawing is while illustrate embodiments of the present invention 2.Fig. 7 is the stereogram of the cylinder 53 of the tumbling-box washing machine 61 of embodiments of the present invention 2.Ball balancer 30 (the first balancer) when Fig. 7 illustrates low speed rotation and the state of ball balancer 62 (the second balancer).
When using when putting into drums inside as a bath towel of washings 13 with wetting state and start dehydration procedure, occur unbalance due to the eccentric load caused by the cloth deflection of washings 13.The size that this is unbalance is arrow 40.Do one's utmost to eliminate by the eccentric load generation of ball balancer 30 (the first balancer) and ball balancer 62 (the second balancer) by the method for controlling rotation utilizing control part 56 to change cylinder 53 unbalance.
