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 generate 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 and lint generation, etc., 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.

[0009] Furthermore, a problem that clothes put in the washing net during washing interferes with cloth movement of the clothes outside the washing net to increase wash unevenness and deteriorating washing power. There is a problem in that the clothes in the laundry net have insufficient detergency and the wash unevenness increases when the clothes get 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 maintenance of the washing machine are simple, and cleanliness is maintained. It is to provide a fully automatic washing machine that can be used.

[0013]

A first feature of the present invention is as follows.
A washing and dewatering tub having a stirring blade at the bottom, an outer tub rotatably enclosing the washing and dewatering tub, a support device for supporting the outer tub in vibration isolation, and driving the stirring wing and the washing and dewatering tub. A laundry storage unit comprising a driving device and washing the desired laundry out of the laundry put into the washing and dewatering tub without mixing with other laundry. In a fully automatic washing machine provided on the inner periphery of
At least a part of the garment storage body is constituted by a mesh member, and the mesh member is constituted by a 100% polyester yarn or a combination yarn of a plurality of different materials mainly composed of polyester.

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.

The mesh member is made of 100% polyester
Because it is composed of yarn or at least a plurality of yarns of different materials mainly composed of polyester, clothing that is very stable against chemicals such as detergents, bleaching agents, and soft finishing agents used in general washing A container can be provided.

A second feature of the present invention resides in that a thread having a thickness of 30 to 150 deniers composed of at least two filaments is used for the mesh member.

With such a configuration, wear on the surface of the clothes container caused by the cloth moving force of the clothes put into the washing and dewatering tub, and catching of a metal object such as a zipper which is inadequate for general clothes. Clothes that are firm against tearing and that are in the clothes storage can be washed without damaging the cloth and losing shape.

A third feature of the present invention is that the fineness of the mesh of the mesh member is set to 50 μm to 100 μm.

With such a configuration, the flow of lint between the clothes storage body and the washing and dewatering tub can be cut off.
If you put socks or stockings in the clothes storage where lint is anxious, the lint will not adhere even if you wash towels that are likely to produce lint at the same time in the washing and dewatering tub. Can be reduced.

A fourth feature of the present invention is that an inner peripheral mesh member on the side facing the laundry in the washing and dewatering tub and an outer peripheral mesh on the side facing the inner peripheral portion of the washing and dewatering tub are provided. The object of the present invention is to form each of the shape members with a different thread thickness or a different eye fineness, or with a different thread thickness and a different eye fineness.

According to such a configuration, for example, the outer-mesh-side mesh member does not directly receive the cloth-moving force of the clothes in the washing and dewatering tub as compared with the inner-mesh-side mesh portion, so that it has a low rigidity. Since it is possible, the outer peripheral side member can be set with an inexpensive member having a simple knitting structure, and the manufacturing cost can be reduced.

According to a fifth feature of the present invention, a frame portion having a greater rigidity than the mesh member is formed on the outer periphery of the mesh member of the garment container, and the frame portion of the mesh member is The thickness and / or the fineness of the yarn near the contact portion are different from those of the portion other than the vicinity of the contact portion.

With such a configuration, the knitting structure of the mesh member is set to be solid near the frame and to be flexible at other portions, so that the cloth moving force of the clothes put into the washing tub is set. Therefore, it is possible to provide a clothing storage body having high rigidity and high detergency.

A sixth feature of the present invention resides in that the mesh member has a structure having elasticity.

With this configuration, the slack amount of the mesh member can be kept constant irrespective of the amount of clothing in the clothing storage, so that unnecessary tensile force or frictional force can be prevented from being applied to the clothing storage. .

A seventh feature of the present invention resides in that at least a part of the clothes housing is colored lightly.

With such a configuration, it is possible to provide a clothing storage body having a clean appearance when the position of the clothing storage body can be instantaneously recognized.

Erupts from

Reference numeral 61 denotes a clothes storage body attached to the inner peripheral portion of the washing and dewatering tub 2 which is a main part of the present invention. This is for putting in and washing clothes which are preferably not mixed with ordinary laundry such as clothes which are worrisome.

At this time, ordinary clothes represented by underwear, towels, and everyday clothes are directly thrown into the washing and dewatering tub 2 for washing.

Here, the rated capacity of the garment storage body 61 may be about 5% to about 10% of the rated washing capacity, and is preferably set to 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 highest water level that can be set in the washing machine, the washing water level L indicates the lowest 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 to be exposed at the lowest water level, so that even when the washing water level is low, washing using the clothes storage body 61 is possible.

Next, as shown in FIG. 3, the clothes storage body 61 is mounted so as to follow the inner peripheral portion of the washing and dewatering tub 2.

As shown in FIG. 5, the inner net 61a and the outer net 61b formed of a fine mesh having a function of washing water distribution and filtration, and an inner frame made of synthetic resin, as shown in FIG.
The washing and dewatering tub 2 is formed into a flat, substantially bag-like shape along the inner peripheral surface of the washing / dewatering tub 2.

Here, the inner net 61a and the outer net 61b
Is determined in consideration of thread material, thread thickness, stitch selection, antibacterial / mildewproof treatment, coloring treatment, securing elasticity, and the like, thereby improving performance as described later.

An opening 61d which can be freely opened and closed by utilizing the elasticity of the synthetic resin is provided in the upper part of the clothes storage body 61.

Here, in addition to the above-described means, the opening 61d may be provided with a fastener or a part of the clothing storage body 61 detachably, or may be provided with a lock mechanism to open inward.

Further, a frame 6 made of synthetic resin is provided on the outer peripheral portion.
The clothing storage body 61 secures appropriate overall rigidity and elasticity by the group configuration of 1c and 61i.

FIG. 5 shows a schematic shape and a frame structure of each frame. The inner net 61 is attached to the inner frame 61c.
a, the outer net 61b is fixed to the outer frame 61i by ultrasonic welding, and then both frames with the net are fixed by ultrasonic welding.

At this time, a separate button 6 made of a synthetic resin is used to open and close the upper clothing outlet.
At 1k, each net is fixed to each frame to make it rigid enough to be easily opened and closed.

Here, the method of fixing each net to each frame may be insert molding or the like in addition to ultrasonic welding. The net may be formed in a bag shape in advance, or two nets may be stacked and fixed to the frame on one side. After that, both frames may be fixed.

FIG. 6 is a sectional view taken along the line aa in FIG. 4 of the present embodiment.

As shown in this figure, the inner peripheral side of the clothes storage body 61 has an inclined surface on the outer frame 61i, and the outer peripheral side has a gentle inclined surface on the inner frame 61c. Because it is made thinner with a convex size of 10 mm to follow the inner circumference, it inhibits the movement of clothing outside the clothing storage body 61,
It does not reduce the cleaning effect.

The U-shaped portion of the garment storage body 61 excluding the opening 61d is superposed over the entire circumference by two welding ribs 611 and 61m, as shown in FIG. The inner welding rib 611 is ultrasonically welded via an inner net 61a and an outer net 61b to fix the net and also fix the inner frame 61c and the outer frame 61i.

The outer peripheral welding rib 61m is attached to the inner frame 6
The synthetic resin 1c and the outer frame 61i are ultrasonically welded directly to each other to secure the welding strength of the clothing storage body 61.

Further, a labyrinth structure is provided inside the inner peripheral welding rib 611, the net is bent, and fitting is performed by a claw. The net is worn by the cloth movement of the clothes in the washing and dewatering tub 2. Even if the net is pulled, excessive force acts on the welded portion to prevent the net from breaking or coming off.

The opening 61d of the clothing storage body 61 is
Each of the nets is ultrasonically welded to each frame by the button-shaped separate member 61k. Like the other parts, the periphery of the welds has a labyrinth structure.

Then, even after the ultrasonic welding, the opening 61d is formed.
The button-shaped separate member 61k has a shape in which button-shaped portions to be spot-welded are connected by a band in order to make the opening and closing easy.

[0086] As shown in FIG.
2 on the inner peripheral wall of the washing and dewatering tub 2
A garment storage body holder 62 in which a convex portion is inserted, and is fixed to a square hole of the body plate 41 at four claws and one screw.
Are provided, and the clothing storage body 61 is mounted on the inner peripheral wall of the washing and dewatering tub 2 by the engagement of the two mounting portions 61e and 61j.

When the clothes storage body is to be mounted, the lower claws 61j are aligned with the clothes storage body holder 62, the inner peripheral wall side of the washing and dewatering tub 2 is raised, and the upper claws 61e are slid downward. , The lower claws 61j are engaged.

When removing, the clothes storage body 61 can be removed by pulling it upward.

As described above, the clothes storage body 61 can be easily attached and detached, thereby simplifying maintenance such as cleaning.

Here, the opening 61d is provided above the clothing storage body 61, and as shown in FIG.
p is formed integrally with the front frame 61c at both sides by, for example, a PP hinge 61q. Is smaller than that of the upper balancer 3 so that the peripheral length of the movable opening 61p is larger.

With this configuration, when closed, there is no fear of clothes jumping out of the clothes storage body 61 because it is adjacent to the lower part of the upper balancer 3, and the clothes storage body 61 travels inward from the upper balancer 3. Since there is no
There is no hindrance to the workability when putting clothes into the washing and dewatering tub 2.

When opened, the movable opening 61p has its elasticity and PP.
Since the hinge 61q is inverted as shown in FIG. 9 and greatly opened inside the upper balancer 3, clothes can be easily taken in and out even when the clothes storage body 61 is attached to the washing and dewatering tub 2. Good washing workability.

As shown in FIG. 6, a plurality of dehydration holes 2a and projections 2c are formed on the body plate 41 located outside the clothing storage body 61.

Next, a basic washing mechanism of the clothes in the clothes storage body 61 will be described.

As described above, of 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 agitating step, the ordinary garment makes a cloth movement such as rotation and up / down switching in the washing and dewatering tub 2 by the rotation of the agitating blades 5.

On the other hand, since the clothes storage body 61 is fixed to the washing and dewatering tub 2, the clothes in the clothes storage body 61 receive a compressive force due to cloth movement of ordinary clothes, and this compressive force becomes a variable load. Therefore, the same effect as the push washing is obtained, and the clothes in the clothes storage body 61 are washed.

Accordingly, the inner net 61a and the outer net 61b are made of a sufficient wear strength and tensile strength against the cloth moving force of ordinary clothes in the washing and dewatering tub 2, and a metallic material such as a zipper attached to the clothes. It is necessary to have a sufficient tear strength against the hooking of steel.

[0099] The strength of the inner net 61a is ensured by an optimum thread thickness and an optimum knitting structure. Although the strength of the yarn increases in proportion to the thickness and the life is prolonged, the rigidity of the net also increases. The above-described push-washing effect depends on the flexibility of the inner net 61a, and an increase in the rigidity of the net causes a decrease in the push-washing effect.
The result is that it is better to set it to about denier.

However, even with 30 to 150 denier yarn,
The use of a single filament causes the above-mentioned increase in rigidity.

Therefore, it is necessary to form the yarn thickness with a plurality of filaments.
A multifilament yarn consisting of filaments in the range of 2 to 6 denier and a yarn having a thickness of 30 to 150 denier are most suitable.

On the other hand, the knitting structure needs to have a knitting structure that is firm against the catch of a metal object such as a zipper provided on the garment, and may be formed of, for example, tricot knitting.

Further, if the setting of the front and the back is wrong, the tear strength is lowered. Therefore, the needle loop surface as the front surface is disposed toward the center of the inner net 61a toward the center of the tank.

Further, since the cloth movement of ordinary clothes in the washing and dewatering tub 2 in the stirring step is dominated by the movement in the rotation direction of the stirring blade 5, the mesh is oriented in the knitting direction 61f in FIG. Ensuring tensile strength against cloth movement and difficulty in catching metal objects.

Further, since the tensile force due to the cloth movement is generally concentrated on the contact portion with the frame portion 61c and in the vicinity thereof,
The thickness knitting structure of the thread of the inner net 61a is
g and the center part 61h.

That is, the frame neighborhood 61g is 150-3
It consists of a thick thread of about 00 denier, and the central part 61h is 3
By composing the thread with a thickness of about 0 to 150 denier,
The inner net 61a which has high rigidity and does not hinder the above-described push-washing effect can be provided.

The inner net 61a has sufficient flexibility and slack. This is inner net 6
This is because the above-mentioned push-washing effect is not reduced by the rigidity of 1a.

Further, by providing the inner net 61a with flexibility and elasticity, it is possible to obtain an optimum push-washing effect according to the amount of clothing in the clothing storage body 61.

That is, when the amount of clothes in the clothes storage body 61 is small, the amount of protrusion of the inner net 61a toward the center of the tank is small, so that cloth movement inhibition of ordinary clothes outside the clothes storage body 61 is minimized. At the same time, the compressive force due to the cloth movement of ordinary clothes is reduced, and an appropriate push-washing effect suitable for the amount of clothes in the clothes storage body 61 can be obtained.

Further, the slack amount of the inner net 61a can always be kept constant irrespective of the amount of clothes in the clothes storage body 61.
a can be prevented.

Next, the outer net 61b may be made of the same material and the same rigidity as the inner net 61a. However, if the outer net 61b is set to be hard by the fiber thickness, material, heat treatment, coating, etc., the overall rigidity can be improved. Therefore, the rigidity load of the frame portion 61c can be reduced, and simplification can be achieved. In addition, outside net 61b
Can be set to have lower rigidity than the inner net 61a because it does not directly receive the compressive force and the abrasion force due to the cloth movement of ordinary clothes in the washing and dewatering tub 2.

Therefore, the cost can be reduced by making the outer net 61b inexpensive with the minimum rigidity required.

The material of the inner net 61a and the outer net 61b must be made of 100% polyester or at least a plurality of materials mainly composed of polyester. This is because chemical resistance to detergents, bleaching agents, soft finishing agents, and the like used in general washing is required, and polyester is most suitable in consideration of water resistance, shrink resistance, and the like.

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

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 of the clothes storage body 61 does not submerge, even if an opening such as a zipper or a corner of the clothes storage body is provided on the upper part, damage to clothes outside the clothes storage body is minimized. be able to.

Further, the opening 61d of the garment storage body 61 may be disposed adjacent to and below the upper balancer 3, so that the garment whose opening is opened like a commercially available laundry net by the movement of the garment. It 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 storage body 61 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 outer peripheral end face of the clothes storage body 61 is covered by the clothes storage body holder 62, the other clothes put into the washing and dewatering tub 2 to be washed at the same time can be used as the clothes and dewatering tub 2 and the clothes and dewatering tub 2. It is possible to prevent biting between the two.

In covering the outer peripheral end face, a bead portion 41c may be used as shown in FIG.

In the dewatering step, since the clothes container 61 is mounted on the maximum radius portion of the washing and dewatering tub 2, the centrifugal force acts effectively and the dewatering performance is good.

The aforementioned dewatering hole 2a is for ensuring the dehydration performance of the clothes in the clothes storage body 61, and a washing liquid or the like is stored between the clothes storage body 61 and the washing and dewatering tub 2. It also causes the accumulation of soap scum and has the effect of preventing this.

The aforementioned convex portion 2c is provided for the purpose of improving the washing performance and dehydration performance of the clothes in the clothes storage body 61.

At the time of agitation, the clothes in the clothes storage body 61 receive the clothes inside the clothes storage body 61 to increase the compressing action of the laundry outside the clothes storage body 61. At the time of dehydration, a centrifugal force component is generated. The movement of the water can be effectively performed toward the dewatering holes provided between the convex portions.

Here, the projection 2c may be provided on the outer net 61b, or another member having the projection 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 lint and the like generated during washing, the circulation of the lint in the washing and dewatering tub 2 and the clothes container 61 is cut off. Is done.

The finer the mesh, the more effective it is in preventing the distribution of lint.

However, if the mesh is made finer than necessary,
The size of the mesh is preferably set to about 50 μm to 100 μm because it causes a decrease in water permeability and a decrease in dehydration performance.

[0130] 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 moisture 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 high moisture absorbing material such as a high molecular weight polymer in order to improve the dewatering performance in the clothes storage body 61.

The inner net 61a and the outer net 61b contain thiazoline or, preferably, an additive having an antibacterial / antifungal effect, such as an imidazole antibacterial material.

The method of incorporating the antibacterial material into the polyester fiber is generally a method in which the antibacterial material is fixed to the raw material of the knitted net by post-processing. By constructing the embedded synthetic yarns at substantially equal intervals at a rate of several to several tens of percent, or by forming copper-containing fibers at substantially equal intervals instead of the synthetic yarns, the antibacterial power is reduced. Sustainability can be improved.

As a result, it is possible to reduce the breeding of bacteria and the occurrence of mold, without the need for drying and drying, as in the case of a commercially available laundry net, and to maintain cleanliness.

On the other hand, when considering the dehydration operation, if the clothes storage body 61 is simply installed, the balance of the washing and dehydration tub 2 which is a rotating body may be lost, and normal dehydration operation may be difficult.

For this reason, as shown in FIG. 3, the clothes storage body 61 mounted on the washing and dewatering tub 2 and the circulation path 47 for collecting lint are provided.
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, a circulation path 47 'and a circulation path cover 48' which are located on the opposite side of the circulation path 47 eject the washing liquid without attaching the net 51 for collecting lint. , And the circulation path 47 are provided at opposing positions 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.

Thus, even when the clothes container 61 is mounted in the washing and dewatering tub 2, the balance is maintained with respect to the dehydrating shaft 11b of the washing and dewatering tub 2, and vibration and noise during dehydration, and during the dehydrating operation. Problems such as stopping can be prevented.

In the present embodiment, the size of the clothes container 61 which does not hinder the cloth movement of the clothes in the washing and dewatering tub 2 is 50% or less in total with respect to the inner wall circumference of the washing and dewatering tub 2. It is known experimentally that the capacity is good, so that the rated capacity of the clothes storage body 61 is 200 g each, and 400 g of two pieces (5% of the rated washing capacity) is considered. On the other hand, the total of the two was set to 37%.

Incidentally, when actually using the clothes storage body 61 for washing, it is necessary to put the laundry into both clothes storage bodies 61 approximately 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.

Light colors such as light blue, light purple, and light pink are suitable for the hue. In order to prevent discoloration during normal washing and color transfer to clothing, the color fastness 4 to 5 is required,
Desirably, No. 5 is optimal.

In addition, even when dyes eluted from blue jeans, red towels, and the like among general clothes are transferred to the inner net 61a and the outer net 61b, the dyes are changed to the light colors such as light blue, light purple, and light pink. By coloring in advance, it is possible to reduce filthiness due to color transfer.

The nets of both nets may have different hues so that they can be used, for example, for sweaters or socks.

Further, a sub-housing unit may be provided above the garment housing 61 for clothing such as a brassiere, which tends to lose its shape. The reason why the sub-housing unit is provided above is to reduce the pressure caused by centrifugal force outside the clothing housing 61 during dehydration.

Next, in actual washing, the performance of the present invention is compared with that of the case where a conventional commercially available washing net is used.

As for laundry, consider a case where delicate clothing such as lingerie, stockings and blouses and ordinary clothing such as underwear, towels and everyday clothes are simultaneously washed.

The fully automatic washing machine used has a rated capacity of 7 kg, and the amount of laundry to be loaded is 80% of the 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 conventional washing using a commercially available washing net, delicate clothes are put into the washing net and put into the washing and dewatering tub 2.

In the product of the present invention, the delicate garments are divided into two garment storage bodies 61 almost equally by 0.2 kg.

The washing method is adapted to the clothes directly put into the washing and dewatering tub 2.

In the case of ordinary clothes, a standard washing course as shown in FIG. 11 is generally programmed in the washing machine, and both of them select the standard course.

In the stirring step, the stirring blade 5 is rotated left and right at a standard reversal cycle, and the clothes directly put into the washing and dewatering tub 2 are moved by the rotation of the stirring blade 5 and rotated in the washing and dewatering tub 2. Make cloth movements such as movement and up / down switching.

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

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

When a conventional washing net is used, the washing net moves in the same manner as the cloth movement described above in order to be put into the washing and dewatering tub 2 together with other laundry, but the washing net has one large size. Since the clothes have the same shape as the bulky clothes, they tend to be entangled with other laundry in a bun-like manner, thereby hindering the entire cloth movement.

As a result, a sufficient cloth movement cannot be obtained, so that the unevenness of washing is increased as compared with a case where both the clothes inside and outside the washing net do not use the washing net, and the washing performance is deteriorated.

[0160] In some cases, the laundry net is protruded from the other laundry, and in this case, sufficient mechanical force cannot be obtained and the laundry net is not immersed in the washing liquid. The detergency of the clothes inside will be extremely reduced.

Further, since the washing net itself is placed under standard stirring conditions, it is subjected to the same mechanical force as ordinary clothes, such as twisting, expansion and contraction, and cloth entanglement, and is therefore protected by the net. However, the cleaning performance in a delicate clothing-only course such as a soft course increases cloth damage, out of shape, and wrinkles.

Further, during stirring by these mechanical forces, the zipper of the washing net may be opened and the garment may jump out.

Since the washing net is one large lump, it tends to be unbalanced in the washing and dewatering tub 2.

As a result, when the process shifts to the dewatering process, vibration and noise may be increased. In the worst case, the tub swings and the safety switch operates to stop the dehydration operation halfway. There is also.

When the washing net is located at the center of the washing and dewatering tub 2, the dehydrating power of the clothes in the washing net may be weakened.

On the other hand, the washing mechanism of the present invention is basically a push washing method as described above, and the clothes storage body 61 has an appropriate rigidity and is mounted in a shape following the inner peripheral wall of the washing and dewatering tub 2. Therefore, the clothes in the clothes storage body 61 do not become entangled with other clothes put into the washing and dewatering tub 2 to be washed at the same time in a dumpling manner and do not hinder the movement of the whole cloth.

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

Further, the garments in the garment 61 are hardly affected by friction, twist, expansion and contraction, and mechanical force entangled with other garments caused by stirring.
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. 9 shows the results of a cleaning performance comparison test under the above-described 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. 10 is a comparison of cloth damage performance of delicate clothing.

In FIG. 9, the dashed line indicates the average cleaning power, and the length of the bar indicates the washing unevenness. The average cleaning power of ordinary clothes is not much different, but the cleaning power of delicate clothes is mixed washing. While A is the best, delicate garments have the worst fabric damage, because the delicate garments have too strong a detergency.

When the commercially available laundry net B is compared with the product C of the present invention, the average detergency is almost the same for ordinary clothes and delicate clothes. The result was that there was little unevenness in washing and that there was minimal damage to the cloth.

As described above, according to the present invention, superior cleaning performance can be obtained as compared with the prior art.

On the other hand, if stockings and socks that are worried about the attachment of lint are also put into the clothes storage body 61 and washed, even if towels that easily produce lint are washed in the washing and dewatering tub 2 at the same time. Infiltration of lint can be prevented, and a good finish can be obtained.

FIGS. 12 and 13 show another embodiment. FIG. 12 shows a case in which the clothes storage body 61 is directly mounted on the washing and dewatering tub 2 without using the clothes storage body holder 62. ,
The number of parts can be reduced by attaching the clothes storage body 61 with the claws 61f and the engagement holes 2d.

FIG. 13 shows the inner net 61a and the outer net 61.
b are separated and each has a frame portion 61c.

The outer net 61b is attached to the washing and dewatering tub 2 by elastic attachment, the inner net 61a is pivotally supported on the outer net 61b so that the bottom side can be rotated, and the upper side is connected to the outer net 61b.
To be hit.

In this case, the integral molding of the net and the frame is facilitated and the productivity is improved. In some cases, the frame may be made of polypropylene and the bottom side may be made of polypropylene and an integral hinge.

[0180]

According to the present invention, clothes that are worried about damage to the cloth and clothes that are worried about generation and adhesion of lint can be washed simultaneously with ordinary laundry, and vibration and noise during dehydration can be reduced. It is possible to provide a fully automatic washing machine free from problems such as stopping during the dehydration operation and jumping out of the clothes from the washing net.
