Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is suitable for washing clothes which need to be separated and washed together with other clothes, such as delicate clothes and clothes which are liable to generate lint. A fully automatic washing machine.

[0002]

2. Description of the Related Art A characteristic of the washing machine market in recent years is that the ratio of the fully automatic washing machine to the total demand of the washing machine is growing rapidly, and among the fully automatic washing machines, the washing capacity of 6 kg or more is large. The capacity type is becoming mainstream.

[0003] Behind this, there is an increasing awareness of rationalization of housework due to an increase in the number of employed housewives, an increase in demand for large-scale washing, and an increase in the number of laundry items due to a desire for cleanliness. The need for batch washing has increased, as we want to wash them all at once.

[0004] However, when considering batch washing, there is a problem in practice that delicate clothes suffer from cloth damage, out of shape, and attachment of lint from clothes that are liable to produce lint. It was an inhibiting factor.

[0005] In contrast to the above-mentioned defective items in the collective washing, in the conventional washing, separate washing is performed in which the cloth is separated into cloth damage, lint generation, and the like, and is separately washed. It has been practiced to put clothes that are concerned about the adhesion of garments into a commercially available washing net and wash them.

[0006] Also, there has been known a washing machine in which a small-sized second washing tub is incorporated in the first washing tub so as to be able to perform separate washing and accessory washing.

[0007]

However, in the above-mentioned separate washing, a plurality of washing courses must be performed, so that additional running costs such as washing time, electricity, water, and detergent are required. Had a problem.

Further, in the washing using the washing net, it is necessary to prepare, dry and clean up the washing net each time it is used, so that the washing operation is troublesome, and the washing net is easily shifted in the washing tub during stirring. , It becomes unbalanced, increasing vibration and noise during dehydration, and in the worst case,
There is a problem that the dehydration operation stops halfway.

Further, there is a problem that the clothes put in the laundry net during washing hinders the movement of the clothes outside the laundry net to increase the unevenness of washing and decrease the washing power. There is a problem that the washing power of the clothes in the laundry net is insufficient and the unevenness of washing increases when the user gets on the clothes.

[0010] Further, there has been a problem that the zipper of the washing net is opened during stirring and the garment in the washing net pops out, and there is also a problem that the dewatering power of the garment in the washing net is weak.

[0011] In the apparatus having the second washing tub, it is necessary to attach and detach the second washing tub each time clothes are taken in and out of the first washing tub. Storage when not using the washing tub was also a problem.

An object of the present invention is to eliminate the above-mentioned disadvantages,
Conventionally, you can wash separately or wash your clothes using a commercially available laundry net. Power and dewatering power are ensured, and there are no problems such as vibration and noise during dehydration, stoppage during dehydration operation, etc. In addition, washing workability such as taking in and out of laundry and cleaning of the washing machine are easy and cleanliness is maintained. It is to provide a fully automatic washing machine that can be used.

In a fully automatic washing machine including a drive unit, a clothes container in which a desired laundry among laundry to be put into the washing and dehydrating tub can be washed without being mixed with other laundry is provided. It was installed on the inner circumference of the washing and dehydrating tub.

With this configuration, when desired clothes are put into the clothes storage body, the other clothes directly put into the washing and dewatering tub can be used without using other commercially available washing nets and other accessories. Since the clothes can be held in the washing and dewatering tub without being mixed, the clothes in the clothing storage can be separated from the clothes directly put into the washing and dewatering tub.

Further, since direct contact with the agitating blades and the inner peripheral wall of the washing and dewatering tub can be prevented, the clothing in the clothing storage is hardly subjected to direct mechanical force such as friction and twist caused by agitation. Since it does not become entangled with clothing outside the storage body, it is possible to obtain a cleaning result in which damage to the cloth, shape loss and wrinkling are suppressed.

Further, since the clothes storage body is mounted on the inner periphery of the washing and dewatering tub, the cloth movement of the clothes outside the clothes storage body simultaneously washed by the clothes storage body like a commercially available washing net is hindered. The washing performance of the laundry outside the clothes storage body is not reduced.

Further, since the clothes storage body and other clothes do not become entangled in a dumpling shape, there is no danger that the clothes in the clothes storage body will fly out.

Further, since the clothes storage body is attached to the inner periphery of the washing and dewatering tub, it is possible to effectively exert a dehydrating force on the clothes inside.

Further, if small items such as handkerchiefs and socks are washed in the clothing storage body, they can be easily taken out without being mixed with many other clothing items.

A second feature of the present invention is that at least a part of the clothes container is made of a member having a filtering action such as a mesh, and its filtering performance is a problem that occurs during washing and is a problem in practical use. The purpose is to be able to collect lint, etc.

With such a configuration, it is possible to block the flow of the lint between the clothes container and the washing / dehydrating tank.

The upper end of the body plate 41 is formed into a curl shape, and a small diameter portion 41a is provided to increase the section modulus.

The upper balancer 3 and the lower balancer 4 each have a hollow ring shape, and a liquid such as salt water is enclosed in the inner balancer. The unbalance due to the deviation of the laundry generated in the washing / dehydrating tank 2 after the stirring process is caused. On the other hand, it is for performing a smooth dehydration operation by working so as to balance during the dehydration process.

The upper balancer 3 has a skirt portion 3 on the outer peripheral portion.
a, and fitted to the small diameter portion 41a of the body plate 41,
Fix at 3. By providing the small diameter portion 41a, the outer diameter of the skirt portion 3a is made substantially the same as the outer diameter of the central portion of the body plate 41, so that the gap with the inner peripheral surface of the outer tub 6 is not reduced.

The lower balancer 4 is arranged so as to be enclosed in the bottom plate 42, and fixed from below the bottom plate 42 with screws 44.

The lower balancer 4 is particularly effective against the imbalance generated at the bottom of the washing / dehydrating tub, and as the washing capacity increases, the unbalance occurring at the bottom of the washing / dehydrating tub also becomes large, and vibrations during dehydration and Noise is also proportional to this.

Therefore, the lower balancer is effective in a washing machine having a large washing capacity and a washing machine intended for low noise.

Erupts from

Reference numeral 61 is a clothing container mounted on the inner peripheral portion of the washing / dehydrating tub 2 which is an essential part of the present invention. It is for putting clothes into which it is preferable to avoid washing together with ordinary laundry such as clothes that are worrisome.

At this time, ordinary clothes such as underwear, towels and everyday clothes are put directly into the washing / dehydrating tank 2 and washed as usual.

Here, the rated internal capacity of the clothes container 61 may be about 5% to about 10% of the rated washing capacity, and preferably about 5%. It should be noted that the rated capacity of the clothing storage body 61 is at the washing water level H as described later.

In FIG. 2, the washing water level H indicates the maximum water level that can be set by the washing machine, the washing water level L indicates the minimum water level, and the vertical dimension of the clothes container 61 is as shown in FIG. It is set so as not to be submerged at the highest water level and not exposed at the lowest water level, and it is possible to wash using the clothes container 61 even when the washing water level is low.

Next, as shown in FIG. 3, the clothes container 61 is mounted so as to follow the inner peripheral portion of the washing / dehydrating tub 2.

As shown in FIG. 5, the overall shape is composed of an inner net 61a and an outer net 61b which are fine meshes having the function of circulating and filtering washing water, and which extend along the peripheral surface of the washing / dehydrating tub 2. It has a flat, substantially bag-like shape.

At the upper part of the clothes container 61, a clothes inlet / outlet having an opening 61d that can be opened and closed by an opening / closing means such as a fastener is formed.

Here, in addition to a fastener or the like, the opening 61d may be a detachable part of the clothing storage body 61, or may have a lock mechanism to open inward.

Further, a frame portion 61c made of synthetic resin is provided on the outer peripheral portion to secure appropriate overall rigidity and elasticity of the clothing container 61.

The frame portion 61c is provided with a mounting portion 61e which engages with the clothing container holder 62 fixed to the inner peripheral wall of the washing / dehydrating tub 2 and the clothing container 61 is secured by the engagement of both. It is attached to the inner peripheral wall of the washing / dehydrating tub 2.

Further, the clothing storage body 61 is fixed in the circumferential position by the clothing storage body holder 62, and the taper portion 41b of the body plate 41 and the upper end of the mounting portion 61e are in contact with each other as shown in FIG. By this, the upward movement beyond a predetermined play is suppressed.

Further, as shown in FIG. 3, the convex bead portion 41c provided on the body plate 41 and the frame portion 61c are brought into contact with each other to prevent downward movement beyond a predetermined level.

Further, the clothing container holder 62 and the mounting portion 61.
As shown in FIG. 4, the engagement of e is an uneven fitting when viewed from above and below, and the upper balancer 3 is provided with an inclined surface 3b as shown in FIG. Clothing storage 61
When wearing, the elasticity is utilized to insert the clothes storage device holder 62 obliquely from above along the inclined surface 3b, and when removing it, pull it obliquely upward to remove it. In this way, the clothing storage body 61 can be easily attached and detached, and the maintenance of cleaning or the like is simplified.

Here, the opening 61d is provided above the clothes container 61 and the inclined surface 3b is provided on the upper balancer 3, so that the clothes container 61 is attached to the washing / dehydrating tank 2. The clothes can be taken in and out even in the state, and the workability in washing is good.

FIG. 6 is a perspective view of the attachment portion of the clothes container 61 and the washing / dehydrating tub 2.

Body plate 41 located outside the clothing container 61
A plurality of dehydration holes 2a and convex portions 2c are formed in the.

Next, a basic cleaning mechanism for the clothes in the clothes container 61 will be described.

As described above, in the laundry to be washed once,
Desired clothing is put in the clothing storage 61, and ordinary clothing, which occupies most of the other clothing, is directly put into the washing and dewatering tub 2.

Next, in the agitation step, ordinary clothes make a cloth movement such as rotation and up / down switching in the washing / dehydrating tub 2 by the rotation of the agitating blades 5.

On the other hand, since the clothes container 61 is fixed to the washing / dehydrating tank 2, the clothes in the clothes container 61 receive a compressive force due to the cloth movement of ordinary clothes, and this compressive force becomes a fluctuating load. Therefore, the same effect as the push washing can be obtained, and the clothes in the clothes container 61 are washed.

Here, the inner net 61a has sufficient flexibility and gives slack. This is because the rigidity of the inner net 61a does not decrease the above-described push-washing effect.

The reason why the garment storage body 61 is formed in a flat shape is to prevent the cloth movement of ordinary garments from being hindered and to reduce the effect of cleaning the inside and outside of the garment storage body 61.

Thus, even when the clothes storage body 61 is not used, it is not necessary to remove the clothes storage body 61, and the washing workability is good.

Further, since the clothes can be held securely by making the clothes storage body 61 into a bag shape, if small articles such as handkerchiefs and socks are put into the clothes storage body 61 and washed, many other clothes can be obtained. It is easy to take out small items without being mixed.

Further, since the upper end portion of the clothing storage body 61 does not submerge, even if an opening such as a fastener or a corner of the clothing storage body is provided on the upper portion, damage to clothing outside the clothing storage body is minimized. be able to.

Further, the opening 61d of the clothing container 61 may be arranged below the upper balancer 3,
The opening of the opening can be prevented by the movement of the clothes from opening the opening like a commercially available laundry net, and the clothes can be prevented from jumping out.

Further, since the clothes storage body 61 has an appropriate rigidity as described above, it is possible to prevent the clothes from being entangled with other clothes put into the washing and dewatering tub to be washed at the same time, and from being turned up.

Further, since the clothing storage body 61 covers the outer peripheral end surface by the clothing storage body holder 62 and the bead portion 41c, the other clothes put in the washing / dehydrating tank 2 to be washed at the same time are washed / dewatering tank 2 as well. It is possible to prevent biting between the clothes storage body 61 and the clothes storage body 61.

When covering the outer peripheral end face, the bead portion 41c and the clothing container holder 62 may be formed in a substantially U shape as shown in FIGS.

The outer net 61b may be made of the same material and the same rigidity as the inner net 61a, but the rigidity of the whole can be improved by setting it to a harder one depending on the thickness of the fiber, the material, the heat treatment, the coating, etc. The rigidity load of 61c can be reduced, and simplification can be achieved.

In the dewatering process, the clothes container 61 is mounted on the maximum radius of the washing / dehydrating tank 2 so that the centrifugal force acts effectively and the dewatering performance is good.

The above-mentioned dehydration hole 2a is for ensuring the dehydration performance of the clothes in the clothes container 61, but the washing liquid or the like is accumulated between the clothes container 61 and the washing / dehydrating tub 2. It also causes the accumulation of soap residue, which is also effective in preventing this.

The above-mentioned convex portion 2c is provided for the purpose of improving the cleaning performance and the dehydration performance of the clothes in the clothes container 61.

During stirring, the clothes in the clothes container 61 receive a larger amount of compression by the laundry outside the clothes container 61. At the time of spin-drying, centrifugal force is generated, so that the clothes in the clothes container 61 are included. The water that is moved can be effectively moved toward the dehydration holes provided between the convex portions.

Here, the convex portion 2c may be provided on the outer net 61b, or another member having the convex portion may be interposed.

Since the meshes of the inner net 61a and the outer net 61b are selected to have a size capable of filtering thread waste generated during washing, the flow of thread waste in the washing / dehydrating tub 2 and the clothing container 61 is blocked. To be done.

[0120] Also, the clothes storage 6
The lint in 1 can be prevented from jumping out of the dewatering hole 2a and flowing out to the drainage path.

If the mesh of the inner net 61a is set finer than the mesh of the outer net 61b, the area of direct contact between the clothes in the clothes container 61 and the clothes put into the washing and dewatering tub 2 is further reduced. Therefore, it is possible to improve the effect of preventing color transfer of a color object and preventing re-adhesion of dirt on a dirt object.

Further, by preventing the mesh of the outer net 61b from being made finer than necessary, it is possible to reduce the resistance when water contained in the clothes in the clothes storage body 61 moves by centrifugal force during dehydration.

At this time, the material of the outer net 61b may be made of a highly moisture-absorbing material such as a high-molecular polymer in order to improve the dewatering performance in the clothes storage body 61.

Further, the inner net 61a and the outer net 61b are made of synthetic resin such as polyester having excellent chemical resistance and abrasion resistance, and are effective in antibacterial / mold prevention such as thiazoline or preferably imidazole antibacterial material. Contains additives.

As a result, unlike a commercially available laundry net, it is possible to reduce the proliferation of bacteria and the generation of fungi without the need for drying after use, and keep cleanliness.

On the other hand, in consideration of the dehydration operation, if the clothes container 61 is simply installed, the balance of the washing / dehydrating tank 2 which is a rotating body may be lost, and normal dehydration operation may become difficult.

For this reason, as shown in FIG. 3, a clothes container 61 to be attached to the washing / dehydrating tank 2 and a circulation path 47 for collecting thread waste.
These structures are arranged so as to be in equilibrium with the dehydrating shaft 11b of the washing and dewatering tub 2.

For example, in FIG. 3, the circulation passage 47 'and the circulation passage cover 48' located on the opposite side of the circulation passage 47 spout the washing liquid without mounting the yarn waste collecting net 51. The circulation path 47 is provided at a position facing the circulation path 47 at equal intervals. In addition, two clothes storage bodies 61 are provided at opposing positions at equal intervals in the circumferential direction of the body plate 41.

As a result, even if the clothes container 61 is mounted in the washing / dehydrating tub 2, a balance can be maintained with respect to the dewatering shaft 11b of the washing / dehydrating tub 2, vibration and noise during dewatering, and during the dehydration operation. It is possible to prevent problems such as stopping.

Incidentally, when actually using the clothes storage body 61 for washing, it is necessary to put the laundry into both clothes storage bodies 61 almost equally, but the weight of the laundry is reduced every time the clothes are stored. It is troublesome to measure. In order to solve this, a guide for the weight of each garment and a combination table of distribution may be described in the instruction manual.

The hues of the inner net 61a and the outer net 61b are colored so that their positions can be easily identified.

The hues of the two nets may be different so that they can be used for sweaters and socks, for example.

A sub-storing body portion may be provided above the clothing storing body 61 for clothes such as a brassiere whose shape is easily lost. The sub-container portion is provided above in order to reduce the pressure applied to the outside of the clothing container 61 by the centrifugal force during dehydration.

Next, in actual washing, the performances of the present invention and the case of using the conventional commercially available laundry net will be compared.

As for laundry, consider a case where delicate clothes such as lingerie and stockings and blouse and ordinary clothes such as underwear, towels and daily wear are simultaneously washed.

The fully-automatic washing machine used has a rated capacity of 7 kg, and the load laundry is 80% capacity of 5.6 kg.
Among them, delicate clothing is set at 0.4 kg, and ordinary clothing is directly put into the washing and dewatering tub 2.

In the conventional washing using a commercially available laundry net, delicate clothes are put in the laundry net and put into the washing / dehydrating tub 2.

In the product of the present invention, delicate clothes are put into the two clothes containers 61 in an amount of approximately 0.2 kg.

The washing method should be adapted to the clothes put directly into the washing / dehydrating tank 2.

In the case of ordinary clothes, since a standard washing course as shown in FIG. 9 is generally programmed in the washing machine, both of them select this standard course.

In the stirring process, the stirring blade 5 is rotated left and right in a standard reversing cycle, and the clothes directly put into the washing / dehydrating tub 2 are moved by the rotation of the stirring blade 5 to rotate in the washing / dehydrating tub 2. Cloth movements such as movements and swapping of top and bottom.

Since the lower laundry moves to the upper laundry which is not near the stirring blade 5, the rotational force of the stirring blade 5 is transmitted, so that the laundry moves while being entangled with each other.

By this movement, the laundry is washed by the mechanical force such as friction, twist, expansion and contraction due to the contact with the stirring blade 5 and the inner peripheral wall of the washing / dehydrating tub 2.

When a conventional laundry net is used, the laundry net is put into the washing / dehydrating tub 2 together with other laundry in the same manner as the above-described cloth movement, but the laundry net has one large size. Since it has the same form as a lump-shaped garment, it tends to entangle with other laundry in a dumpling-like manner and hinder the movement of the entire cloth.

As a result, since the cloth movement cannot be sufficiently obtained, the unevenness of washing becomes large as compared with the case where the laundry net is not used for both the clothes inside and outside the laundry net, and the washing performance is deteriorated.

In addition, the laundry net may be spilled over other laundry, and in this case, sufficient mechanical force cannot be obtained and the laundry net is not immersed in the washing liquid. The washing power of the clothes inside will be extremely reduced.

Further, since the laundry net itself is placed under standard agitation conditions, it receives the same mechanical force as ordinary clothes such as twisting, stretching, entanglement, etc., so it is protected by the net. However, as compared to the cleaning performance in delicate clothing courses such as soft courses, cloth damage, loss of shape, and wrinkles increase.

Further, due to these mechanical forces, the fasteners of the laundry net may be opened and the clothes inside may pop out during stirring.

Further, since the washing net is one large lump, the washing / dehydrating tub 2 is likely to be in an unbalanced state.

As a result, vibration and noise increase when the process goes to the dehydration step, but in the worst case, the shake of the tank increases and the safety switch operates, causing a stoppage of the dehydration operation. There is also.

Further, when the laundry net is located in the central portion of the washing / dewatering tub 2, the dehydrating power of the clothes in the laundry net may be weakened.

On the other hand, the cleaning mechanism of the present invention is basically a push-cleaning system as described above, and the clothes container 61 has a proper rigidity and is mounted in a form that follows the inner peripheral wall of the washing / dehydrating tub 2. Therefore, the clothes in the clothes container 61 are not entangled with other clothes put in the washing / dehydrating tank 2 to be washed at the same time in a dumpling shape and do not hinder the movement of the entire cloth.

As a result, the unevenness of washing of the laundry inside and outside the clothes container 61 can be minimized, and a good washing result can be obtained.

Further, since the clothes in the clothes container 61 are hardly subjected to friction, twist, expansion and contraction caused by agitation, and mechanical force entwined with other clothes, lingerie,
Even delicate clothes such as stockings, blouses, knits, and other fashionable clothes can be put into the clothes storage body 61 to prevent damage to the cloth, entanglement, out of shape, wrinkles, etc. even when using a standard strength water flow. A good cleaning effect can be obtained.

FIG. 7 shows the results of the cleaning performance comparison test under the above conditions.

In the figure, B is a commercially available laundry net, C is the product of the present invention, and A is a mixture of delicate clothes and ordinary clothes and washed.

FIG. 8 is a comparison of the cloth damage performance of delicate clothes.

In FIG. 7, the alternate long and short dash line shows the average detergency, and the length of the bar shows the unevenness of washing. Although the average detergency of ordinary clothes is almost the same, the detergency of delicate clothes is mixed. On the other hand, A is the best, but the delicate clothes have the worst damage to the cloth.

Comparing the commercially available laundry net B and the product C of the present invention, the average cleaning power of both ordinary clothes and delicate clothes is almost the same, but the unevenness of the product C of the present invention is compared to the unevenness of washing of the commercially available laundry net B. The result was less uneven washing and the least damage to the cloth.

From the above, according to the present invention, excellent cleaning performance can be obtained as compared with the prior art.

On the other hand, if stockings, socks, etc. which are worried about the attachment of lint are also put in the clothes container 61 and washed, even towels that are likely to produce lint can be washed in the washing / dehydrating tank 2 at the same time. Intrusion of lint can be prevented and a good finish can be obtained.

FIGS. 10, 11 and 12 show another embodiment. In FIG. 10, the clothes container holder 62 is not used and the clothes container 61 is directly attached to the washing / dehydrating tank 2. With the claw 61f and the engagement hole 2d, the clothing storage body 61
By installing, the number of parts can be reduced.

FIG. 11 shows a substantially U-shaped clothing container holder 6.
The hook 6 of the substantially box-shaped clothing container 61 is fitted into the second fitting hole 62a.
The clothing storage body 61 is attached and detached by engaging 1 g and rotating it toward you.

The stopper is formed by fitting the claw 61h and the hole 62b, and in this case, the attachment / detachment of the clothing container 61 is easier.

FIG. 12 shows the net (inside) 61a and the net (outside).
61b is a separate body, and each frame portion 61c
