and an operation panel box 9 provided above the outer frame 1 using the upper opening edges of the washing tub 3 and the water receiving tank 4 to control various operations such as washing, rinsing, spin-drying, and draining. .

The main rotor blade 6 includes a disk-shaped blade body 10 and a blade body 1
A protruding body 11 protruding above the center of 0 and a protruding body 1
1 and a cap body 12 attached to the tip of the cap body 1. The cap body 12 is equipped with a magnet having a strong magnetic force as an insert or the like.

A small-capacity second washing tub 13 that is detachably supported at the upper opening edge of the washing tub 3 is placed so as to be dropped into the inner upper part of the washing tub 3. In other words, separate washing chambers divided into upper and lower sections are constructed. As shown in FIG. 2, the second washing tub 13 is provided with rotary blades 14 at the inner bottom of the tub, and the rotary blades 14 are rotatably supported by a shaft 15.

The second washing tub 13 is made of synthetic resin, and the shaft 15 is fixed by insert molding.
16 is a washer, 17 is a presser fitting, and 18 is a set screw.

A slit 19 is formed in the side wall of the second washing tub 13, and a drain valve is provided at the bottom. This drain valve is composed of a drain hole 20 and a plug 21 that is attached to and detached from the drain hole.

A magnet is inserted into the rotary blade 14.
This magnet and the magnet contained in the cap 12 constitute a clutch of a magnetic coupling.

When the second washing tub 13 is placed above the washing tub 3, the main rotor blade 6 and the rotor blade 14 are connected to each other via the clutch.
are connected, and the rotation of the main rotor blade 6 is transmitted to the rotor blade 14. 2nd washing tub 13 to washing tub 3
The clutch can be released by removing it from the top.

Next, the usage pattern of this washing machine will be explained.

(1) When washing items at once Thin items and thick items, colored items and white items, heavily soiled items and normally soiled items, small and medium sized items and large items, etc., should be washed separately.

Thin items such as underwear are placed in the second washing tub 13, and thick items such as exercise clothes, jumpers, and pants are placed in the washing tub 3 for washing.

Colored items such as jeans and skirts should be placed in washing tub 3.
White items such as blouses and slips are stored in the second washing tub 13.
Put them in each and wash them.

Small and medium-sized items such as Y-shirts, T-shirts, towels, and handkerchiefs are placed in the second washing tub, while large items such as sheets, towel bags, pajamas, and blankets are placed in the washing tub 3.

Heavily soiled items such as work clothes or diapers are placed in the washing tub, and lightly soiled or normally soiled items are placed in the second washing tub 13 for washing.
You can also put it in the opposite direction depending on the amount of washing, disposal of waste water, etc.

In this way, you can wash different items at once depending on the type of items you want to wash. Since the conventional washing machine without a second washing tub 13 can wash the clothes twice, it can be washed at once, so the washing time can be shortened and the washing machine is easy to use.

The washing operation from loading the laundry to the washing tub 3 and the second washing tub 13 is performed as follows.

First, the second washing tub 13 is removed and the items to be washed are placed in the washing tub 3. After putting detergent there, the second washing tub 13 is set on top of the washing tub 3, and the items to be washed and the detergent are put into this washing tub 13 in that order. If the items to be washed are selected and placed in the second washing tub 13 in advance, detergent may be added before setting them on the washing tub 3.

After doing this, the washing tub 3 and the second washing tub 1
3. Pour water up to the specified water level. The washing tub 3 may be filled with water before the second washing tub 13 is set.

Thereafter, by setting the dial on the operation panel box 9 and operating the washing motor 7, the main rotor blade 6 and the rotor blade 14 rotate together. In this way, the washing in the washing tub 3 and the second washing tub 13 are done separately at the same time.

Drain the water after washing.

Normally, we want to wash colored or heavily soiled items in the washing tub 3 located below, so we drop the washing water from the second washing tub 13 into the washing tub 3 and drain it together with the washing water from the washing tub 3. There is no problem. Second
The washing tub 13 is drained by removing the plug 21 of the drain hole 20.

Colored or heavily soiled items should be removed from the second washing tub 13.
When washing in the washing tub 3, the second washing tub 13
Remove it from the tank, carry it to the drain, and throw away the water you want to wash. Since the second washing tub 13 has a small capacity, it is lightweight, small, and easy to carry.

If it is difficult to carry the second washing tub 13,
The washing water may be dropped into the washing tub 3 and drained together with the washing water in the washing tub 3. Even if the washing water in the second washing tub 13 mixes with the washing water in the washing tub 3 for a short period of time until draining is finished, color transfer and dirt transfer are unlikely. When washing diapers, etc., it is unsanitary, so it is better to dispose of the washing water into the drain instead of dropping it into the washing tub 3.

Dehydrate after draining.

The items to be washed are taken out of the second washing tub 13 and placed in the dehydration tub 5. The second washing tub 13 may be removed and the items to be washed in the second washing tub 13 may be dropped into the dehydration tub 5.

After completing dehydration in the dehydration tank 5, the items to be washed are taken out and transferred to the second washing tank 13.

The items to be washed in the washing tub 3 are also dehydrated in the same manner as described above.

The dehydration may be performed on the items to be washed in the second washing tub 13 and the items to be washed in the washing tub 3 together.

The time required for spin-drying is short, and after spin-drying, the clothes are transferred to the second washing tub 13 and washing tub 3 separately, so there is almost no color transfer.

After dehydration, perform rinsing and final dehydration.

Rinsing and final dehydration are carried out in the same manner as the previous washing and dehydration.

For items other than colored items that have been washed separately,
A good way to use it is to remove the second washing tub 13, and then rinse it in the washing tub 3 as well as dehydrating it all at once.

After washing is finished, the second washing tub 13 can be used as a washing basket.

Water may be poured into the washing tub 3 and the second washing tub 13 in the following manner.

Unplug the stopper 21 of the second washing tub 13, and
Water is poured into the washing tub 13. Water does not accumulate in the second washing tub 13 and falls into the washing tub 3. When the washing tub 3 is filled with water to a predetermined water level, the water can be stored in the second washing tub 13 by closing the drain hole 20 with the stopper 21.

(2) When washing a small amount of laundry When washing leftovers or washing a small amount, the second washing tub 13 is used. It is also preferable to use the second washing tub 13 when washing small items such as handkerchiefs, towels, and baby clothes. Using this washing tub saves washing water and detergent.

That is, it has been conventional practice to adjust the amount of water and detergent to be washed depending on the amount of items to be washed. However, if you use too little water just because you don't have many things to wash, you won't be able to wash them properly. This is because the fabric gets damaged and the items being washed get on top of the rotary blades and spin around idly. For this reason, if a small number of items are washed in the washing tub 3 having a large capacity, the amount of water to be washed cannot be reduced very much, resulting in a lot of waste of water and detergent.

Since the second washing tub 13 has a small capacity, the washing tub 3
Even if the amount of water is small, the second washing tub 1
The amount of water is sufficient for 3. Wash thoroughly. Since the amount of water is small, the appropriate detergent concentration required for washing can be obtained with at least the amount of detergent. This way, you can save on water and detergent used for washing.

Drainage, dehydration, rinsing and final dehydration after washing are carried out as described above.

Rinse thoroughly with plenty of water. The rinsing time is also short. When such rinsing is desired, a washing tub 3 with a large capacity is used.

(3) When washing a large amount of laundry When washing a large amount of laundry at once, remove the second washing tub 13 and use the washing tub 3. Since the washing tub 3 from which the second washing tub 13 is removed can be used up to the top, it is possible to wash a large amount of laundry at once like a normal washing machine.

In this way, this washing machine can wash separate items at the same time, saves water and detergent when washing a small amount, and is easy to use because it can wash many items at once like a normal washing machine.

(4) When washing three or more separate items For example, when washing white items, red items, and black items, you can save water and detergent by doing the following.

First, a white item to be washed is placed in the second washing tub 13, detergent is added, and water is poured. Washing motor 7
I drive the car and wash it. When you finish washing, do not throw away the washing water. Transfer the items to be washed on the white background to the dehydration tank 5, and transfer the items to be washed in the red area to the second tank.
into the washing tub 13. The dewatering motor 8 and the washing motor are operated to perform washing and dewatering in parallel. Spin drying will finish faster, so leave it as it is until you finish washing. After washing is finished,
Pour clean water into washing tub 3. You can save time by pouring water while washing. The white laundry items that have been dehydrated are transferred to the washing tub 3, and the red laundry items that have been washed are transferred to the dehydration tank 5. The water to be washed is left in the second washing tub 13, and the black laundry is put therein, and then the dehydration motor 8 and the washing motor 7 are operated to perform washing and dehydration in parallel. Washing, rinsing, and dehydrating are all done at the same time.

Since the dehydration ends before washing and rinsing are completed, the red laundry is transferred to a bucket or the like and the dehydration tank 5 is emptied.

The rinsed white laundry items are transferred to the dehydration tank 5, and the red laundry items are instead transferred to the washing tank 3 to perform dehydration, washing, and rinsing in parallel. You will need to wash black clothes twice, so if there is a risk of damage to the fabric, rinse it and wash it in the second washing tub 13.
If you remove it, you will only have to wash it once.

The dehydration of the white laundry is the final dehydration, so
Once the dehydration is complete, take it out of the dehydration tank 5 and transfer it to a basket or the like to prepare for the next drying.

The black clothes to be washed are taken out from the second washing tub 13 and transferred to the dehydration tank 5 to be dehydrated. After the black laundry items have been dehydrated, the black laundry items are transferred from the second washing tub 13 to the dehydration tank 5 and dehydrated. After dehydration, the black-based laundry items are taken out from the dehydration tank 5, the red-based laundry items that have been rinsed are transferred to the dehydration tank 5,
Instead, put black items to be washed into the washing tub 13,
Perform dehydration and rinsing at the same time. After the final dehydration of the red laundry items is completed, the laundry items are transferred to a basket or the like, and the dehydration tank 5 is emptied before the black laundry items are rinsed. After rinsing the black laundry items, the laundry items are immediately transferred to the dehydration tank 5 for final dehydration of the red laundry items. In this way, you can complete the three types of separate washing.

In this way, in the order of washing in the second washing tub 13, dehydration in the dehydration tank 5, rinsing in the washing tub 3, and final dehydration in the dehydration tank 5, wash items with a white background that will not lose color first, and then wash items with color-fast colors last. By washing clothes with a black background that does not transfer easily, you can save on washing water, detergent, and rinsing water. This is because the second washing tub 13 and the washing tub 3 are divided into washing and rinsing tubs, and the same washing and rinsing baths can be used repeatedly. The reason why the rinsing water can be used repeatedly is that the washing liquid is well shaken out into the dehydration tank 5, so there is less dirt in the rinsing water, and the volume of the washing tub 3 is smaller than that of the second washing tub 13.
This is because it is larger than , and can store a large amount of rinsing water. Also, since spin-drying, rinsing, and washing are done in parallel, the time it takes to finish all washing is shortened.

Next, we will discuss water supply rinsing.

A plug 21 is placed in the drain hole 20, the drain valve is closed, and water supply is continued. When the water level in the second washing tub 13 reaches the slit 19, water flows out from the slit 19 and falls into the washing tub 3.

By rotating the rotary blade 14 while causing water to flow out from the slit 19 in this manner, water supply rinsing can be performed.

The second washing tub 13 shown in FIG.
2 is formed. The outer dewatering tank 33 shown in FIG. 1 communicates with the overflow port of the washing tub 3.

When water supply and rinsing are performed in the second washing tub 13 shown in FIG. The water is drained to the outside of the washing machine through the Therefore, when water supply rinsing is performed using the second washing tub 13 shown in FIG. 3, the rinsing water does not enter the washing tub 3, so washing in the washing tub 3 can be performed in parallel with the water supply rinsing. can.

A mounting receiving part 34 is provided at the top of the washing tub 3. A mounting portion of the second washing tub 13 is supported here. The attachment portion is formed on the outer side of the upper edge flange portion 33.

A device consisting of a vertical dehydration tank and a dehydration motor that drives this dehydration tank.A small-capacity second washing tank is placed inside the upper part of the washing tub, and the washing tub is placed on top of the washing tub. A mounting part is formed on the upper part of the second washing tub to be received by the mounting receiving part, and rotary blades are provided at the inner bottom of the second washing tub, and the second washing tub is partitioned into upper and lower parts. A second
By attaching the washing tub to the washing tub, a clutch is provided that connects the main rotary blade on the washing tub side and the rotating blade on the second washing tub side, and a drain valve for draining water is provided at the bottom of the second washing tub. , is characterized in that a slit for overflowing water is provided on the upper side of the second washing tub.

According to this, there are the following advantages.

(1) When doing multiple washes, washing, dehydration, rinsing, and final dehydration can be done in parallel, so the overall time required to finish washing can be shortened.

(2) Since there is a second washing tub and a washing tub, it is divided into washing and rinsing, and the same washing and rinsing liquid can be used repeatedly, so washing water, detergent, and rinsing water can be saved.

(3) Shake off the washing liquid well in the dehydration tank, then
Because of rinsing, there is less rinsing water, and
The volume of the washing tub is larger than that of the second washing tub, and it can store more rinsing water, so it rinses well.

(4) Since the second washing tub is provided with a drain valve, the water in the second washing tub can be drained while the washing tub is set in the washing tub, so there is no need to take the trouble of removing the second washing tub from the washing tub. Drainage work is extremely easy.

(5) A slit for overflowing water is provided in the second washing tub, so water can be rinsed while continuously pouring water.
Since the second washing tub is used to wash small items, sufficient rinsing can be achieved by simply supplying water and rinsing without dehydrating after washing. It's convenient because you don't have to transfer the items you want to wash.
