Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washing method and a washing aid suitable for washing clothes that easily lose their shape with a washing machine.

[0002]

2. Description of the Related Art When washing clothes that are easily deformed, such as sweaters and fashionable clothes, with a washing machine with water, in order to prevent the laundry from being out of shape due to a water flow swirling in a washing tub,
Laundry nets are used.

[0003] However, even when laundry is stored in the laundry net, the laundry is not properly prevented from being out of shape because the laundry is shifted or curled in the laundry net.

Japanese Patent Laid-Open Publication No. Hei 7-289778 has a hanger inserted into a net, and a laundry is hung on the hanger to prevent the laundry from being out of shape. In addition, Japanese Utility Model Registration No. 3017510 discloses a sheet-like substrate that is inserted into a net, and stores laundry in the net in a state of being folded along the substrate to prevent the laundry from being out of shape. I'm trying.

[0005]

However, since the hanger in the net does not have a shape-retaining function for a part of the laundry such as a sweater or a shirt collar or a shoulder, it is difficult to sufficiently prevent the shape from being lost. I couldn't. Further, since the sheet-like substrate in the net does not have water permeability, there is a problem that washing water does not sufficiently pass through the laundry and dirt cannot be sufficiently removed. Further, since the hanger has no water permeability, the collar, which is one of the most heavily soiled parts, could not be sufficiently washed.

[0006] It is an object of the present invention to provide a washing method and a washing aid which can solve the above problems.

[0007]

According to the washing method of the present invention, a shape retaining annular member having greater rigidity than the covering water-permeable member is provided in a storage space formed by the covering water-permeable member. The laundry is stored, and in the stored state, the laundry is washed by a washing machine. Furthermore, it is preferable that the specific gravity of the shape-retaining annular member is set so that the laundry can be prevented from floating on the surface of the washing water. According to the method of the present invention, the laundry stored in the storage space formed by the covering water-permeable member covers the shape-retaining annular member having a greater rigidity than the covering water-permeable member. Washed by. Thus, the shape-retaining annular member can prevent the laundry from being out of shape during the washing. Further, since the shape-retaining annular member is annular, the washing water can pass through the inner peripheral side, thereby allowing the washing water to sufficiently flow through the laundry,
Dirt can be sufficiently removed. In addition, by preventing the laundry from floating on the surface of the washing water by the shape-retaining annular member, the washing water is more reliably passed through the laundry more reliably,
Dirt can be sufficiently removed.

In the method of the present invention, the laundry is preferably stored in the storage space in a state of being folded along the periphery of the shape-retaining annular member. Thus, the laundry can be folded using the shape-retaining annular member into a form that does not easily lose its shape during washing, and can be washed in the folded state.

[0009] The shape-retaining annular member is preferably attached to the outer periphery of the shape-retaining water-permeable member. This allows
Not only the shape-retaining annular member but also the shape-retaining water-permeable member can prevent the laundry from being out of shape, and can maintain the water-permeability on the inner peripheral side of the shape-retaining annular member, thereby lowering the washing effect. Never.

Preferably, the shape-retaining water-permeable member is formed of a flexible net having less rigidity than the shape-retaining annular member. This can prevent the laundry from being damaged by the shape-retaining water-permeable member.

At least one of the covering water-permeable member and the shape-retaining water-permeable member has a flexible surface-side net and a flexible surface-side net that is spaced from the surface-side net. And a net on the back side having the above structure. As a result, the front-side net is elastically displaced relative to the back-side net, thereby alleviating the relative movement of at least one of the covering water-permeable member and the shape-retaining water-permeable member with respect to the laundry. it can. Therefore, it is possible to prevent the laundry from being rubbed by the net and being hurt, pilling, and fluffing. In this case, one end of each of the plurality of elastically deformable linear portions is connected to the net on the front side, and the other end is connected to the net on the back side, so that both nets can be relatively displaced elastically. It is preferable that a gap is formed between the respective linear portions. As a result, the water flow can pass between the net on the front side and the net on the back side, so that the water flow passing through the laundry can be increased and the washing effect can be improved.

It is preferable that the laundry is sandwiched between the covering water-permeable members. Accordingly, the shape of the laundry during washing can be prevented by sandwiching the laundry with the water-permeable member. In this case, the outer periphery of each of the pair of covering water-permeable members is attached to the covering annular member having a greater rigidity than each covering water-permeable member, and both covering annular members are attached to the laundry by the both covering water-permeable members. It is preferable that elasticity is applied to the laundry by elastically deforming the nets constituting the respective coating water-permeable members that sandwich the laundry so as to sandwich the laundry. Thus, the laundry can be sandwiched by the elasticity exerted by both nets, so that the shape of the laundry can be reliably prevented.

In the method of the present invention, it is preferable that the relative displacement of the water-permeable member for coating with respect to the washing tub of the washing machine is regulated. By restricting the relative displacement of the covering water-permeable member with respect to the washing tub, it is possible to prevent the covering water-permeable member from moving around due to the water flow swirling at the time of washing, thereby also preventing the laundry from being out of shape. Further, it is possible to prevent the laundry from rubbing each other to prevent fluff, pills, and shrinkage, and to wash laundry such as a sweater for which dry cleaning is recommended with a general-purpose washing machine.

The laundry assisting device according to the present invention includes a shape retaining annular member that is covered with laundry, and has a storage space formed by a covering water-permeable member that is less rigid than the shape retaining annular member. The laundry that covers the shape-retaining annular member can be stored. According to the laundry auxiliary tool of the present invention, the method of the present invention can be performed.

[0015] The washing aid of the present invention includes a shape-retaining water-permeable member formed of a flexible net having less rigidity than the shape-retaining annular member. Preferably, the shape-permeable water-permeable member is attached to the outer periphery of the shape-permeable water-permeable member, the shape-retainable water-permeable member is foldable, and the shape-retaining annular member is elastically bendable and twistable. Thereby, when carrying out the method of the present invention, the shape of the laundry can be prevented from being out of shape even by the shape-retaining water-permeable member, and the water-permeability on the inner peripheral side of the shape-retaining annular member can be maintained, so that the washing effect is reduced. That is, the shape-retaining water-permeable member can prevent the laundry from being damaged. In addition, the laundry aid can be stored compactly.

[0016]

Embodiments of the present invention will be described below with reference to the drawings.

First washing aid 1 shown in FIGS. 1 and 2

Are formed with two through holes 2a, 2b.
Covers 2c and 2d, such as cloth, are sewn to the periphery of b. Each of the through holes 2a and 2b is formed for inserting a hook for hanging the laundry together with the first washing auxiliary tool 1 as described later.

The shape-retaining annular member 3 has a higher rigidity than the shape-retaining water-permeable member 2 and a greater specific gravity than the washing water, and is formed of an elastic metal linear member having a flat cross section. By being formed into a square frame shape, it is configured to be elastically bendable and twistable. The shape retaining annular member 3 is covered with a cloth cover 6, and the cover 6 is
Is sewn with a thread (not shown).

In order to carry out washing using the first washing auxiliary tool 1, first, as shown in FIGS. 3 (1) and 3 (2), the first washing Insert the auxiliary tool 1. Thereby, the first laundry auxiliary tool 1 is covered with the laundry 10. Next, the laundry 10 is turned over, and the laundry 10 is folded along the peripheral edge of the shape retaining annular member 3 as shown in (3) of FIG. 3 and (4) of FIG. Although a sweater is shown as the laundry 10 in the illustrated example, the laundry 1
The type of 0 is not particularly limited. For example, in the case of a handkerchief, a neckerchief, or a muffler, the first washing auxiliary tool 1 is attached to the laundry, and the laundry is folded along the periphery of the shape-retaining annular member 3 so that the first laundry auxiliary tool 1 is folded. The first laundry auxiliary tool 1 is covered with the laundry. In the case of a sleeveless garment or the like, the laundry 10 does not have to be folded just by inserting the first washing auxiliary tool 1.

Next, the laundry 10 folded along the peripheral edge of the shape-retaining annular member 3 and covering the first washing auxiliary tool 1 is moved to the second laundry shown in FIGS. Aid 101
In the storage space defined by the water-permeable member 102 for coating.

The second washing auxiliary tool 101 includes a coating water-permeable member 102 composed of a pair of nets, and a coating annular member 103 to which the outer periphery of each coating water-permeable member 102 is attached. , Both covering annular members 10
And 3 connecting fasteners 104.

Each covering water-permeable member 102 is foldable, is knitted from a flexible resin fiber, for example, and has a lower rigidity than the shape-retaining annular member 3. The space between the two water-permeable members 102 is a storage space for the laundry 10. As shown in FIG. 5, a pocket P may be provided in one or both of the coating water-permeable members 102 to enable storage of small items.

Each of the covering annular members 103 is larger in rigidity than each of the covering water-permeable members 102, and, like the shape-retaining annular member 3, is made of an elastic metal linear member having a flat cross section. By being formed into a substantially quadrangular frame shape, it is configured to be elastically bendable and twistable. Each covering annular member 103
Are covered with cloth covers 106, and each cover 106 is sewn to the outer periphery of the covering water-permeable member 102 with a thread (not shown).

The fastener 104 has a pair of cloth ribbons 104a sewn to the respective covers 6 along the outer periphery of the covering water-permeable member 102 with a thread (not shown).
And teeth 104 attached to the periphery of each ribbon 104a
b and a slider 104c. The two annular members 103 are connected to each other by the engagement of the two teeth 104b with each other by the sliding of the slider 104c. In this connected state, both coating water-permeable members 1
02 causes the laundry 10 to be sandwiched. At this time, the elastic deformation of both coating water-permeable members 102 allows elasticity to act on the sandwiched laundry 10. Further, the sliding of the slider 104c releases the meshing of the teeth 104b with each other, so that the laundry 10 can be taken out from between the coating water-permeable members 102.

When one end 104 ′ of the fastener 104 is separated from the other end 104 ″, the fastener 1
In a state where both the annular members for coating 103 are connected by 04, an opening 115 larger than the mesh of each water-permeable member for coating 102 is formed between the annular members for covering 103.

Next, as shown in FIGS. 6A to 6D, inside the washing tub 20 of the washing machine, the two coating water-permeable members 102 sandwich the laundry 10 between the two coating water-permeable members 102. The relative displacement of the water-permeable member 102 with respect to the washing tub 20 can be regulated. That is, (1) in FIG.
The case where the inner peripheral dimension of the washing tub 20 and the outer peripheral dimension of the second washing auxiliary tool 101 substantially match, and the covering annular member 103 is pressed against the inner periphery of the washing tub 20 in a slightly elastically deformed state is shown. . FIG. 6B shows a state in which the outer peripheral dimension of the second washing auxiliary tool 101 is larger than the inner peripheral dimension of the washing tub 20, and the covering annular member 103 is elastically deformed so that the upper surface becomes a convex curved surface. Shows a case in which the tub 20 is pressed against the inner periphery of the washing tub 20. FIG. 6C shows a state in which the outer peripheral dimension of the second washing auxiliary tool 101 is larger than the inner peripheral dimension of the washing tub 20, and the covering annular member 103 is inclined with respect to the horizontal and slightly elastically deformed. Shows a case in which the tub 20 is pressed against the inner periphery of the washing tub 20. 6D, the outer peripheral dimension of the second washing auxiliary tool 101 is larger than the inner peripheral dimension of the washing tub 20,
The case where the covering annular member 103 is pressed against the inner periphery of the washing tub 20 in an elastically deformed state so that the lower surface becomes a convex curved surface is shown. In any case, the friction between the washing tub 20 and the covering annular member 103 causes the two water-permeable members 1 for covering.
02 relative to the washing tub 20 is restricted.

Next, the pulsator 21 is set inside the washing tub 20.
Is rotated to wash the laundry 10 in the storage space.

When the washing by the washing machine is completed, the second
The laundry 10 is taken out from the laundry auxiliary tool 101, and the laundry 10 is dried. At this time, as shown in FIG. 7A, the first washing auxiliary tool 1 is covered with the laundry 10 so that the hook 25 is inserted into one of the through holes 2a and 2b.
The laundry 25 can be hung by hooking the hook 25 on a washing rope 26 or the like. Note that, depending on the shape of the laundry, a hook may be inserted into the other of the through holes 2a and 2b.

When the laundry 10 is folded after being dried, the first laundry auxiliary tool 1 is taken out of the laundry 10, and then the first laundry aid 10 is placed on the inverted laundry 10 as shown in FIG. 7 (2). With the washing aid 1 attached, the shape-retaining annular member 10
3, the laundry 10 is folded, the laundry 10 is turned upside down, and the first laundry auxiliary tool 1 is taken out from the laundry 10 as shown in FIG.
The laundry 10 can be easily folded.

According to the above-described embodiment, the laundry 10 stored in the storage space defined by the water-permeable covering member 102 has the shape-retaining annular member 3 having a greater rigidity than the water-permeable covering member 102. Is washed by the washing machine in a state in which is covered, and the shape-retaining annular member 3 prevents the shape from being lost during washing and washing. In addition, since the specific gravity of the shape-retaining annular member 3 is larger than that of the washing water, the laundry 10 can be prevented from floating on the surface of the washing water. In addition, the washing water can be sufficiently passed through the laundry to sufficiently remove dirt.

In addition to the shape-retaining annular member 3,
The shape-retaining water-permeable member 2 can also prevent the laundry 10 from being out of shape and maintain the water-permeability on the inner peripheral side of the shape-retaining annular member 3, so that the washing effect is not reduced. Further, since the shape-retaining water-permeable member 2 is constituted by a flexible net having a smaller rigidity than the shape-retaining annular member 3, the laundry 10 can be prevented from being damaged.

Further, the laundry 10 can be prevented from being out of shape by sandwiching the laundry 10 between the covering water-permeable members 102, and the relative displacement of the covering water-permeable member 102 with respect to the washing tub 20 can be restricted. Therefore, even if the pulsator 21 rotates at the time of washing to generate a swirling water flow,
The covering water-permeable member 102 can be prevented from moving around in the washing tub 20. Thereby, the water-permeable member for coating 1
02 can be sufficiently prevented from becoming out of shape, and the laundry 10 can be prevented from rubbing against each other to remove fluff, fluff,
Shrinkage can be prevented, and laundry such as sweaters, for which dry cleaning is recommended, can be washed with a general-purpose washing machine. In addition, the water-permeable members for coating 102 can sandwich the laundry 10 by applying elasticity, so that the shape of the laundry 10 can be reliably prevented. In addition, laundry 1
Even if the covering water-permeable member 102 is made of a highly flexible material so as not to damage 0, the covering annular member 103 having a greater rigidity than each of the covering water-permeable members 102 is pressed against the inner periphery of the washing tub 20. Thereby, the relative displacement of the coating water-permeable member 102 with respect to the washing tub 20 can be regulated by the friction between the washing tub 20 and the coating annular member 103.
Further, since the covering annular member 103 is pressed against the inner periphery of the washing tub 20 by elasticity, friction between the washing tub 20 and the covering annular member 103 is increased, and the washing tub of the covering water-permeable member 102 is provided. The relative displacement with respect to 20 can be reliably controlled. In addition, the opening 115 formed between the two annular members 103 in a state of being connected to each other allows the water flow to smoothly enter between the two water-permeable members 102 during washing, thereby improving the washing effect. .

The shape retaining annular member 3 and the covering annular member 1
03 is elastically bendable and twistable. Thus, the shape-retaining water-permeable member 2 and the coating water-permeable member 102
In addition to the fact that the is possible to fold, the washing auxiliary tools 1 and 101 can be stored compactly. For example, as shown in FIG.
Are bent and twisted to obtain points a, b, c, and d in the figure.
Are changed in the order shown by the arrows in the figure, as if 3
Since the two circles can be overlapped, the space for storage, transportation and sale when not in use can be reduced. In particular, when the annular members 3 and 103 are configured by linear members having a flat cross section, the state in which the three circles are overlapped is
Since it can be maintained without being stored in a storage bag or the like and fixed with a string or the like, it is not necessary to use another member to maintain the state.

FIG. 9 shows a first washing auxiliary tool 1 'according to a modification. The difference from the first washing auxiliary tool 1 of the above embodiment is that the first embodiment does not include the shape-retaining water-permeable member 2; The point is that it is constituted only by the shape retaining annular member 3.

FIGS. 10 to 14 show a second washing auxiliary tool 201 according to a modification. This second washing auxiliary tool 201
Covering water-permeable member 2 constituting a laundry storage space in Japan
Numeral 02 has a bag shape having front, rear, left and right side walls, a bottom wall, and an upper opening, and the inside thereof is a laundry storage space S as shown in FIG. A fastener 214 is connected to the covering water-permeable member 202 so that the upper opening can be opened and closed. Further, a suction cup 230 for suction to the washing tub 20 of the washing machine is attached to the coating water-permeable member 202 as described later.

As shown in FIGS. 11 and 12, the covering water-permeable member 202 is made of a flexible surface-side net 2.
31, a flexible back side net 232 that is arranged at an interval D to the front side net 231, and a plurality of linear portions 233 that can be elastically bent and deformed. One end of each linear portion 233 is connected to the net 231 on the front side, and the other end is connected to the net 232 on the back side, so that the two nets 231 and 232 can be elastically relatively displaced. That is, the two nets 231 in a state where they are not relatively elastically deformed as shown in (1) of FIG.
The interval D of the 232 is narrowed as shown in FIG. 13B by the respective linear portions 233 being elastically bent. Each linear part 2
A gap 235 is formed between the 33. Although the mesh shape of each of the nets 231 and 232 is a hexagon in the present embodiment, it is not particularly limited. Each of the nets 231 and 232 is flexible and preferably has appropriate flexibility not to damage the laundry. In the present embodiment, the yarn is formed by knitting a yarn in which a plurality of synthetic resin filaments are twisted. Be composed. Each linear portion 233 is elastically deformable and deformable, and in the present embodiment, each net 231,
232 is formed by alternately connecting synthetic resin filaments thicker and stiffer than the synthetic resin filaments constituting the net 232 to the net 231 on the front side and the net 232 on the back side.

As shown in FIG. 14, the washing tub 20 of the washing machine
, The relative displacement of the coating water-permeable member 202 with respect to the washing tub 20 can be regulated. That is, by adsorbing the plurality of suction cups 230 attached to the coating water-permeable member 202 to the inner periphery of the washing tub 20,
Regulate the relative displacement.

When the second washing auxiliary tool 201 of the above-described modified example is used, the relative displacement of the covering water-permeable member 202 with respect to the washing tub 20 is regulated, so that the laundry 10 stored in the laundry storage space S can be controlled. Since the flow of water passing through is increased, the cleaning effect can be improved. Further, the coating water-permeable member 2
Even if impact from water flow or centrifugal force during dehydration acts on 02,
The net 231 on the front side is elastically displaced relative to the net 232 on the back side, so that the stored laundry 1
The relative movement of the net 232 on the back side with respect to 0 can be reduced. Thereby, it is possible to prevent the laundry 10 from being rubbed by the net 232 and being damaged, causing pills or fluffing, and preventing the laundry 10 from being out of shape. Further, even if the pulsator 21 rotates during washing to generate a swirling water flow, the net 232 can be prevented from moving around in the washing tub 20, thereby also preventing the laundry 10 from being out of shape. Further, since the water flow can pass through the gap 235 between the linear portions 233 connecting the net 231 on the front side and the net 232 on the back side, it passes through the laundry 10 stored in the laundry storage space S. The cleaning effect can be improved by increasing the water flow.

It should be noted that the present invention is not limited to the above-described embodiment and modifications. For example, the covering water-permeable member 102 of the second washing auxiliary tool 101 of the above embodiment may be replaced with the covering water-permeable member 202 of the second washing auxiliary tool 201 of the above-described modification. Further, the shape-preserving water-permeable member 2 of the above embodiment may be replaced with a covering water-permeable member 202 constituting the second washing auxiliary tool 201 of the above-described modified example. In addition, a commercially available general bag-shaped washing net may be used as the second washing auxiliary tool. Further, when the laundry itself has a specific gravity greater than the wash water, the specific gravity of the shape-retaining annular member may be smaller than the wash water, provided that the laundry is set in a range that can suppress the floating of the laundry on the wash water surface. Good.
