[0002]

2. Description of the Related Art Conventionally, a so-called laundry net has been generally used for washing clothes which are easily damaged by a washing machine. In addition, the washing machine is provided with a washing course in which delicate washing and rinsing are performed with a weak stream of water in order to wash clothes such as wool products and thin articles that are easily damaged by cloth.

[0003]

However, even if a laundry net is used, the clothes move and rub against each other in the net, or the rotary blades directly contact the clothes through the mesh of the net, which results in damage to the cloth. Cannot be completely prevented. Further, even if the water flow is weakened in the washing machine, the effect of preventing damage to the cloth is not sufficient. Furthermore, in recent years, detergents for dry items, which can be used to wash Dry Mark clothes at home, have been commercialized. However, this kind of clothes must be washed carefully so as not to damage the cloth or lose its shape. Therefore, it is extremely difficult to wash with a conventional washing machine.

The present invention has been made to solve the above problems, and an object of the present invention is to assist a washing machine capable of remarkably preventing damage or loss of shape of clothes during washing and rinsing. An object of the present invention is to provide a washing tool using the tool and the auxiliary tool.

[0005]

The first invention made to solve the above problems is placed in a washing tub of a washing machine,
An auxiliary tool for a washing machine, which is used for washing or rinsing by placing laundry on its upper surface, comprising a plate-shaped member having a plurality of openings, and the plate-shaped member when placed in a washing tub. And a support member formed on the lower surface of the plate-shaped member so as to be supported at a predetermined distance from the rotary wing at the bottom of the washing tub.

Here, the supporting member is, for example, a rib-shaped projection formed on the entire or a part of the outer periphery of the plate-shaped member, or a pole-shaped leg formed in the central portion of the plate-shaped member, and its height is The size is determined so that the plate member does not contact the rotor blade.

For the reasons described below, it is preferable that the auxiliary machine for a washing machine is constructed so as to float on water. Specifically, the plate member or the supporting member itself is formed of a material having a specific gravity smaller than that of water, for example, lightweight plastic, or a float made of expanded polystyrene is attached to the lower surface of the plate member.

A second invention made to solve the above problems is an auxiliary for a washing machine which is placed in a washing tub of a washing machine and is used for washing or rinsing by placing a laundry on the upper surface thereof. A plate-shaped member having a plurality of openings, and one or more protrusions formed on the lower surface of the plate-shaped member so as to come into contact with the rotating blades at the bottom of the washing tub when placed in the washing tub. It is characterized by having and.

The plate-shaped member in the auxiliary equipment for a washing machine according to the first and second aspects of the present invention is composed of two or more members, which are connected by a hinge-shaped member to form one plate-shaped member, It is preferable that it can be folded as needed. Further, it is preferable that the opening formed in the plate member has a larger opening ratio in the peripheral portion than in the central portion.

A third aspect of the present invention made to solve the above-mentioned problems is an auxiliary tool for a washing machine in which laundry is stored and used for washing or rinsing by putting it in a washing tub. a) an upper surface member having a plurality of openings, b) a lower surface member having a plurality of openings, and c) mounted between the upper surface member and the lower surface member, which is easily deformable and water impermeable, or It is characterized in that it comprises a tubular member made of a material that does not allow water to easily pass therethrough, and d) a floating member attached to the upper surface member.

In the washing machine auxiliary tool according to the third aspect of the present invention, a cushioning member having water permeability is provided on the lower surface of the lower surface member, and a pressing member for pressing the clothes is provided on the upper surface of the lower surface member for the reason described later. It is preferable.

Here, for example, the upper surface member is a net stretched over a frame made of plastic, and the tubular member is also made of a net material.

A fifth invention made to solve the above problems is a washing method for washing and rinsing using any one of the auxiliary equipment for a washing machine according to the first to fourth inventions. In the above, any one of the auxiliary equipment for a washing machine and the laundry is placed in a washing tub, and at least the auxiliary equipment for the washing machine and the entire laundry are poured into the washing tub so as to be submerged in water. It is characterized in that the rotation of the rotor is controlled so that the water flow in the washing tub alternates between strong water flow and weak water flow or stop of water flow.

[0015]

BEST MODE FOR CARRYING OUT THE INVENTION A washing machine auxiliary tool according to the first aspect of the present invention is placed in a washing tub, on which clothes are carefully folded and placed. When water is poured into the washing tub and the rotary vanes are rotated after a predetermined amount of water has accumulated in the wash tub, the rotary vanes generate a vertical water flow, which causes the opening of the plate-shaped member from above. A stream of water passes underneath. Washing (or rinsing) is performed as this stream of water passes through the clothing.

While the rotor blades are rotating, the garment is pressed against the plate member by the force of the water flow from above, and is maintained in the initially placed state. That is, the clothing does not lose its shape. Although the force of the water flow is weakened while water is being injected or while the rotary blades are stopped, it is desirable that the clothes are gently fixed on the plate member at this time as well. If the assisting device itself is made to float on the water, the assisting device floats in the water with the clothes placed thereon when the force of the water flow does not act. That is, buoyancy acts on the upper surface of the plate-shaped member to gently fix the clothes, and it is possible to prevent the clothes from being separated from the plate-shaped member and losing their shape.

The auxiliary member for a washing machine according to the second aspect of the invention is placed in a washing tub, and the clothes are placed on the upper part in a state of being carefully folded. When water is poured into the washing tub and a certain amount of water is accumulated in the washing tub and then the rotor is rotated, the protrusions collide with the rotating rotor, and the reaction of the protrusion causes the assisting device to lift the clothes. Levitate in the water while being placed on. However, the force of the water flow passing through the opening of the plate-shaped member from the top to the bottom causes the assisting tool to sink, so that the assisting tool repeatedly rises and falls. At this time, washing (or rinsing) is performed with water passing through the clothes.

In order to stably hold the clothes on the plate-shaped member, it is preferable that these plate-shaped members have a size close to the inner diameter of the washing tub. But,
Generally, since the balance ring is attached to the inside of the upper end of the washing tub which also serves as the dehydration tub, the inner diameter thereof is small. Therefore, when the plate-shaped member is made of a material that does not easily bend, it is extremely difficult to put the auxiliary tool in the washing tub. Therefore, it is preferable that the auxiliary tool be folded into a small state when it is put in the washing tub, and that the auxiliary tool be put in the washing tub and then unfolded and placed at an appropriate position.

Further, the water flow in the washing tub becomes stronger in the central portion closer to the rotor. On the other hand, in order to wash the clothes on the plate-like member uniformly, it is preferable that the amounts of water passing through the plurality of openings are equal to each other as much as possible. Therefore, in order to balance the strength of the total amount of water, increase the opening area of the opening in the peripheral part where the water flow is weak, that is, in the part near the inner peripheral wall of the washing tub, and decrease the opening area in the central part where the water flow is strong. You can

In the washing machine auxiliary tool according to the third aspect of the present invention, the clothes are stored in the auxiliary tool and placed in the washing tub. When water is poured into the washing tub, the buoyancy of the floating member attached to the periphery of the upper surface member causes the entire auxiliary tool to float as the water level rises. When the rotary blade is rotated after a predetermined amount of water has accumulated in the washing tub, the rotary blade causes a vertical water flow, and the water that has entered the auxiliary tool from above through the opening of the top member Through the opening of the lower surface member. Washing (or rinsing) is performed by the water flow at this time. Since the tubular member does not allow water to easily pass through, the water only escapes from the top to the bottom, and due to the action of the floating member, the auxiliary tool only rotates horizontally while maintaining the vertical positional relationship of the auxiliary tool. The clothes are not agitated, and the shape of the clothes is hardly lost.

Further, when the lower surface member of this auxiliary tool is formed of plastic or the like, there is a possibility that noise may be generated due to collision when the rotary blade rotates. However, by attaching a cushioning member such as a thick net to the lower surface of the lower plate member, the generated sound can be reduced.

Further, by loosely fixing the garment by using a pressing member such as a rubber band attached to the upper surface of the lower plate member, it is possible to further prevent the garment from losing its shape.

In the washing machine auxiliary tool according to the fourth aspect of the present invention, the clothes are stored in the auxiliary tool and placed in the washing tub. When water is poured into the washing tub, the entire assisting tool floats as the water level rises due to the buoyancy of the floating member attached to the upper surface member. When the rotary blades are rotated when a predetermined amount of water is collected in the washing tub, the rotary blades generate a vertical water flow, and the water that has entered from above through the net mesh of the top member passes through the clothes and the cylinder Through the net-like member net to the side. Washing (or rinsing) is performed by the water flow at this time. At this time, due to the action of the floating member, the auxiliary tool only rotates in the horizontal direction while maintaining the vertical positional relationship, so that the clothes in the auxiliary tool are not agitated and the shape of the auxiliary tool is hardly lost.

In the above-described washing method of washing or rinsing using the auxiliary equipment for the washing machine, when the rotary blades are rotated so that a strong water flow is generated, the auxiliary equipment and clothes in water are washed by the force of the water flow. Sink toward the bottom of the tank. At this time, because of the aid, the rotary blade does not directly contact the laundry and only the water flow passes through the clothes. Further, when the rotary blade is rotated or stopped so that a weak water flow is generated, the auxiliary tool floats away from the bottom of the washing tub together with the clothes. At this time, the water flow passing through the clothes naturally weakens or almost disappears. By switching the water flow in this manner, a washing effect similar to that of washing clothes by hand is produced.

[0025]

As described above, according to the laundry assisting tool of the first to fourth aspects of the invention, when washing is performed, the clothes are agitated in the washing tub and directly rub against the rotary blades. Disappears and the washing (or rinsing) is carried out by the water flow. Therefore, it is possible to easily wash clothes, such as dry-mark clothes and wool products, which are easily damaged by a washing machine, with almost no damage or loss of shape.

In particular, according to the washing method using the laundry assisting tool according to the present invention, since the push washing is effectively performed, a sufficient washing (or rinsing) effect can be achieved while preventing the cloth from being damaged or losing its shape. Can be obtained.

【Example】

[Embodiment 1] First, the first auxiliary member for a washing machine according to the present invention
An embodiment (hereinafter referred to as "embodiment 1") of No. 1 will be described with reference to the drawings. 1 and 2 show a first embodiment.
FIG. 3 is a sectional view and a perspective view of the clothes stand 10 of FIG. 3, and FIG. 3 is a sectional view of the washing machine for explaining the state when the clothes stand 10 is placed in the washing tub.

In the clothes stand 10, a large number of water passage holes 13 are provided.
Ribs 12 are formed on the outer peripheral portion of the disk-shaped member 11 having the. The height of the rib 12 is such that the clothes stand 1 is placed inside the washing tub 31.
It is determined that the lower surface of the disk-shaped member 11 does not come into contact with the rotary blade 32 when 0 is placed. The disk-shaped member 11 is divided into two parts at substantially the center, and they are connected by a hinge 14 so that they can be folded (see the two-dot chain line in FIG. 1). Further, a material such as lightweight plastic is used for the disk-shaped member 11 and the ribs 12 so that the specific gravity of the clothes stand 10 is smaller than that of water. Further, the diameter of the circular water passage hole 13 is the disk-shaped member 1.
The smaller the central portion of the No. 1 is, the larger the outer portion is formed.

The operation of washing (or rinsing) using the clothes stand 10 having the above structure is as follows. The clothes stand 10 is placed in the washing tub 31 (position indicated by the solid line), and the clothes to be washed are placed thereon. When water is poured into the washing tub 31, water also flows into the outer tub 30 through the dehydration holes formed in the peripheral wall of the washing tub 31, and the water level rises. Since the specific gravity of the clothes stand 10 is smaller than that of water, the clothes stand 10 floats up with the clothes placed thereon (the position of the broken line) as the water level rises. That is, the clothes are held near the water surface while being pushed up by the clothes stand 10 from the lower side.

After the water up to a predetermined water level is accumulated in the outer tub 30, the rotating blades 32 are rotated to perform washing. At this time, the rotation of the motor 33 depends on the rotation of the motor pulley 3
4, belt 35, main pulley 36, and power switching mechanism 37
Is transmitted to the rotary blade 32 via.

Although a specific rotation control of the rotary blade 32 will be described later, the rotary blade 32 is controlled so that rotation and stop are alternately repeated. When the rotary blades 32 are rotated, a water flow from above to below through the water passage holes 13 is generated. Due to the force of this water flow, the lower end of the rib 12 causes the washing tub 31 to
The clothes stand 10 is sunk downward until it contacts the bottom.
When the rotary blades 32 are stopped and the water flow becomes gentle, the clothes stand 10 floats upward again. Therefore, when the rotating blades 32 are alternately rotated and stopped at appropriate intervals, the clothes stand 10 moves up and down in water as indicated by the double-headed arrow in FIG. 3 with the clothes placed thereon. When the water flow passes through the water passage hole 13 from the top to the bottom, the water passes through the clothes (see the arrow in FIG. 3), whereby the clothes are pressed and washed (or rinsed).

In order to uniformly wash the entire clothes,
The same amount of water can pass through the water hole 1 at any position on the clothes stand 10.
Passing 3 is desirable. Therefore, the diameter of the water passage hole 13 is reduced in the central portion where the water flow is strong due to the rotor blades 32, and the diameter of the water passage hole 13 is increased in the outer peripheral portion where the water flow is weak to prevent the water flow from being biased toward the center portion. You can press and wash the entire clothes with equal force.

In general, the washing tub 3 also serving as a dehydrating tub
A balance ring 38 for balancing the washing tub 31 is attached to the inside of the upper end of the washing tub 1.
1 The inner diameter of the upper end is smaller than the inner diameter of the lower side. Therefore, it is difficult to put the clothes stand 10 having a diameter close to the inner diameter of the washing tub 31 into the washing tub 31 as it is. Therefore, the washing tub 3 is folded in half at first.
It is put in 1, spread in it, and placed on the bottom of the washing tub 31.

[Embodiment 2] Next, a clothes stand according to a second embodiment (hereinafter referred to as "embodiment 2") will be described. 4 and 5 are cross-sectional views and perspective views of the clothes stand 10 according to the second embodiment, and FIG. 6 is a cross-sectional view of the washing machine for explaining the state when the clothes stand 10 is placed on the washing tub. In the second embodiment, instead of the rib 12 of the first embodiment, a leg portion 15 that contacts the central portion of the rotary blade 32 is provided.

The function and operation of the clothes stand 10 of the second embodiment at the time of washing are almost the same as those of the first embodiment. When the clothes stand 10 is placed in the washing tub 31, the legs 15 are located substantially on the center of rotation of the rotary wings 32, and the clothes stand 10 sinks due to the rotation of the rotary wings 32, that is, the downward water flow. When it is inserted, the lower end of the leg portion 15 comes into contact with the central portion of the rotary blade 32.

The clothes stand 10 of the second embodiment may be partially folded as in the first embodiment so that it can be easily put into the washing tub 31. Further, for example, the disc-shaped member 11 may be formed of a soft polyethylene resin or the like so that the disc-shaped member 11 can be bent when being put in the washing tub 31. However, in this case, it is necessary to prevent the outer edge portion of the disk-shaped member 11 from being deflected by its own weight or the weight of the clothes and colliding with the rotary wing 32 when installed on the bottom of the washing tub 31. Therefore, the disk-shaped member 11 has a structure in which a part of the outer peripheral edge thereof is slightly extended further outward, and a protrusion for holding the expanded portion is formed inside the lower portion of the washing tub 31 to form a protrusion. It is preferable to support the outer edge portion. A guide groove may be formed inside the washing tub 31.

[Third Embodiment] Next, a clothes stand according to a third embodiment (hereinafter referred to as "third embodiment") will be described. 7 and 8 are cross-sectional views and perspective views of the clothes stand 10 of the third embodiment, and FIG. 9 is a cross-sectional view of the washing machine for explaining the state when the clothes stand 10 is placed on the washing tub. In the third embodiment, instead of the rib 12 of the first embodiment or the leg portion 15 of the second embodiment, one or more protrusions 1 are provided on the off-center lower surface of the disk-shaped member 11.
6 are provided. Further, a notch 17 is formed around the outer edge of the disk-shaped member 11.

The protrusion 16 is formed at a position where it contacts the rotary blade 32 when the rotary blade 32 rotates. Notch 17
In order to prevent the clothes stand 10 from rotating with the flow of water, the clothes stand 10 is provided at a position fitted to a protrusion such as a circulating water channel inside the washing tub 31.

The function and operation of the clothes stand 10 of the third embodiment during washing are different from those of the first and second embodiments. That is, the clothes stand 10 of Examples 1 and 2 moves vertically in water due to the water flow and the buoyancy of the clothes stand. On the other hand, in the clothes stand 10 according to the third embodiment, when the rotary wings 32 rotate, the protrusions 1
6, the clothing stand 10 floats upward by the reaction. However, since the force that pushes down the clothes stand 10 downward is applied by the water flow from above, the clothes stand 10 immediately sinks. Therefore, the clothes stand 10 repeatedly rises and falls while the rotary wings 32 rotate, and at this time, the water hole 1
Wash (or rinse) clothes with water that passes 3
Is done.

[Embodiment 4] The above-mentioned Embodiments 1 to 3 are auxiliary tools for placing clothes on the disk-shaped member 11, and the following fourth and fifth embodiments (hereinafter, "Embodiment 4", respectively) "Embodiment 5" is a bag-shaped auxiliary tool for storing clothes therein. 10 and 11 are a cross-sectional view and a perspective view of a clothes washing bag 20 of Example 4 of the auxiliary machine for a washing machine according to the present invention,
FIG. 12 is an explanatory view of a state in which the clothes washing bag 20 is placed in the washing tub.

The clothes washing bag 20 is composed of an upper disk-shaped member 21, a lower disk-shaped member 23, and a cylindrical member 24 each having a hollow portion formed around the outer edge thereof. The upper disk-shaped member 21 and the lower disk-shaped member 23 are made of a material such as hard plastic which is hard to be deformed, and the tubular member 24 is made of a material such as a cloth or a vinyl sheet which is soft and easily deformed but hard to pass water. The water passage hole 13 is formed in each of the disk-shaped members 21 and 23.

A ring-shaped float 22 such as foamed polystyrene is adhered to the hollow portion of the upper disk-shaped member 21, which gives buoyancy to the upper disk-shaped member 21 and the entire clothes-washing bag 20 floats in water. It is possible to prevent it from turning upside down in water. Further, the lower disk-shaped member 23
A cushioning material 25, such as a net cloth, that allows water to pass through well is attached to the lower side. The cushioning material 25 is for cushioning the sound when the lower disk-shaped member 23 collides with the rotary blade 32 during washing (or rinsing). Further, inside the tubular member 24, a rubber band 26 for gently fixing clothes to the lower disk-shaped member 23 is provided. An opening / closing opening 27 is provided on the side surface of the tubular member 24 so that clothes can be taken in and out.

The operation of washing (or rinsing) using the clothes washing bag 20 having the above structure is as follows. The clothes are fixed in the clothes washing bag 20 with the rubber band 26 and placed in the washing tub 31. When water is poured into the washing tub 31, the buoyancy of the float 22 causes the clothes washing bag 20 to float as shown in FIG. 12 (the position of the broken line). After the water up to a predetermined water level is stored in the outer tub 30, the rotating blades 32 are rotated to perform washing (or rinsing).

When the rotary blades 32 rotate, water passes through the water passage holes 13 of the two disk-shaped members 21 and 23 from the top to the bottom as in the case of the first embodiment. Sink. When the rotary blades 32 are stopped and the water flow becomes gentle, the clothes washing bag 20 floats upward again. Therefore, when the rotating blades 32 are alternately rotated and stopped at appropriate intervals, the clothes washing bag 20 moves up and down in water as indicated by double-headed arrows in FIG. Since water cannot pass through the tubular member 24 (or does not pass through at all), the water moves only in the up-down direction, and the water flow pushes (or rinses) clothes. As described above, even if the clothes washing bag 20 sinks and temporarily collides with the bottom of the washing tub 31 or the rotary wings 32, the cushioning material 25 does not produce a loud noise.

Further, since the lower disk-shaped member 23 is not easily deformed, it is unlikely that the rotary blades 32 come into contact with the clothes, but even if the clothes slightly protrude from the water passage hole 13, the cushioning material 2
If 5 is provided, it is possible to avoid the rotary wings 32 from directly hitting the clothes.

It should be noted that the elastic band structure in which the clothing in which the tubular member 24 is bellows-shaped and accommodated therein is lightly sandwiched between the two disc-shaped members 21 and 23 does not require the rubber band 26 for holding the clothing. Becomes

Further, the two disk-shaped members 21 and 23 may have a structure in which a net is stretched over a circular frame made of plastic or the like, other than the above-mentioned embodiments.

[Embodiment 5] FIG. 13 is a cross-sectional view of a clothes washing bag of Embodiment 5. The structure of this clothes washing bag 20 is similar to that of the fourth embodiment, but in the fifth embodiment, the upper disk-shaped member 2 is used.
1 and the tubular member 24 are made of a material such as a net cloth that allows water to pass therethrough, and the lower disk-shaped member 23 is made of a material such as cloth or a vinyl sheet that is expected to have a buffering effect and does not allow the passage of water. Since the two disk-shaped members 21 and 23 have a structure that is difficult to deform, a net or cloth is stretched over a circular frame made of plastic or the like. Further, as in the case of the fourth embodiment, a ring-shaped float 2 such as expanded polystyrene is provided around the outer edge of the upper disk-shaped member 21.
2 is attached.

The laundry washing bag 20 of Example 5 has the same effect as that of Example 4, but water enters the bag through the net mesh of the upper disk-shaped member 21 and escapes to the side surface through the net mesh of the tubular member 24. . By this water flow, the clothes in the clothes washing bag 20 are pressed and washed (or rinsed).

Since the lower disk-shaped member 23 is not easily deformed and the clothes do not stick out like a net, it is possible to avoid the rotary wings 32 from directly hitting the clothes.
A collision sound with the rotary blade 32 is hardly generated.

The clothes stand and the clothes washing bag described above are examples, and the shape and the material can be changed as appropriate in accordance with the gist of the present invention.

[Embodiment of Washing Machine] Next, the construction and operation of a washing machine for washing (or rinsing) dry-mark clothes and the like using the auxiliary equipment for a washing machine according to the present invention will be described. To do. FIG. 14 is a block diagram of an electric system of such a washing machine. A key input signal is input from the operation unit 41 and a water level detection signal is input from the water level sensor 43 to the control unit 40 mainly composed of a microcomputer. The control unit 40 has a memory storing an operation program, receives a key input from the operation unit 41, and drives the motor 33 in accordance with a corresponding operation program. The motor drive unit 44, the water supply solenoid valve 45, and the drainage solenoid valve. Control the operation or operation of the 46 or the like. Also, a display is made on the display unit 42 according to the key input signal.

The operation of the washing machine having the above structure is as follows. The operation section 41 has a washing course input key for selecting a washing course in which the washing time and the strength of water flow are predetermined in accordance with the type (cloth quality) of the clothes to be washed and the degree of dirt. It is provided. With the laundry course input key,
For example, you can select "Standard Washing Course", "Solid Washing Course" for washing dirty clothes, and "Dry Washing Course" for washing clothes such as wool products and dry-mark clothes that are easily damaged. It is possible.

The processing operation when the dry laundry course is selected by operating this course selection key will be described with reference to the processing flowchart of FIG. It is desirable to prevent the detergent from coming into direct contact with the clothes, because the clothes marked with the dry mark are likely to be damaged or discolored. Therefore, in the dry course, the operator first puts the detergent into the washing tub 31 (step S10). Next, the operator places the clothes stand 10 as in the first embodiment in the washing tub 31 and places the clothes thereon (step S1).
1). When the dry washing course is selected and the start key is operated (step S12), the control unit 40 opens the water supply electromagnetic valve 45 and starts water injection into the washing tub 31 (step S13). Based on the detection signal from the water level sensor 43, when the water level in the washing tub 31 reaches a predetermined wash water level, the water supply solenoid valve 45 is closed and the water injection is stopped (step S).
14).

Next, the control unit 40 controls the motor drive unit 44 to rotate the rotary blades 32 and execute washing (step S15). During the washing operation, the rotation of the rotary blades 32 generates a force of water flow that sinks the clothes stand 10 downward, and the force is maintained for a predetermined time, and the clothes stand 10 is weakened or stopped. It is necessary to alternately create a state in which the surface emerges. for that reason,
Specifically, for example, rotation control is performed such that the motor 33 is turned on / off repeatedly at a cycle of 1.5 seconds / 3 seconds.
In this case, since the water flow is strong enough to sink the clothes stand 10 about 0.5 seconds after the rotary blades 32 start to rotate, the clothes stand 10 is almost at the bottom of the washing tub 31 for about 1 second. , The action of the force of the water flow from above on the clothes continues.

At this time, by alternately reversing the rotating direction of the rotary blades 32, that is, the direction of the water flow acting on the clothes, gentle kneading washing is performed in addition to the push washing, which is an effect of easy washing. Is even higher.

After the washing operation is completed, the control unit 40 opens the drainage solenoid valve 46 to drain the washing tub 31 (step S1).
6). Not only at the time of washing, but at the time of rinsing as well, rinsing suitable for dry-mark clothes and the like is executed by the processing of steps S11 to S16 similar to the above.

Of course, it is possible to set the clothes stand after the detergent is poured and then a little water is injected to dissolve the detergent. Further, the clothes stand may be set after pouring water, but the treatment procedure of FIG. 15 is more preferable in consideration of ease of setting.
