Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a washing machine suitable for washing separately and washing in smaller quantities.

[Conventional technology]

I try to wash discolored or dirty laundry separately from white items. At first,
I have to run the washing machine twice because I wash white items and then wash discolored items and dirty items.

Also, the amount of water and detergent is adjusted to some degree depending on the amount of laundry, but if the amount of water is too small, the laundry will not be washed well. For this reason,
When the amount of laundry is extremely small compared to the standard amount of laundry,
Water and detergent tend to be wasted.

[Problem that the invention seeks to solve]

The object of the present invention is to provide a product that allows laundry to be washed separately without having to be washed twice, saves water and detergent, and allows for easy water treatment after washing. .

[Means for solving problems]

The present invention includes a small-capacity second washing tub that is placed inside the upper part of the washing tub, and a rotary blade that can rotate freely is provided at the inner bottom of the second washing tub, and separate washing tubs are divided into upper and lower sections. By attaching the second washing tub to the washing tub so that the chamber is configured, 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 It has a water valve at the bottom for draining water.

Thereby, the above objective can be achieved.

[Effect]

By attaching the second washing tub to the washing tub,
Since there are two separate washing chambers divided into upper and lower sections, it is possible to separately put the items to be washed in the second washing tub and the washing tub and wash them at the same time. A small amount of laundry can be washed in the second small-capacity washing tub. Since the second washing tub is equipped with a water valve, by opening the water valve, the washing tank can be flushed with water. When it is undesirable to pour water into the washing tub, a second washing tub is built and carried, and the water to be washed is disposed of into the drain.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, the two-tub washing machine includes an outer frame 1 made of steel plate, a base 2 made of synthetic resin on which the outer frame is placed, and a washing tub 3 made of synthetic resin housed in the outer frame 1. , is formed integrally with this washing tub 3, and the outer frame 1
A water receiving tank 4 stored in the washing tank 4, a dehydration tank 5 stored in the water receiving tank 4, a main rotary blade 6 provided at the center of the bottom of the washing tub 3, and a washing motor 7 serving as a drive source for the main rotary blade 6. , a dehydration motor 8 serving as a driving source for the dehydration tank 5
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 7 to control various operations such as washing, rinsing, spin-drying, and watering. .

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 water valve is provided at the bottom. This water 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 rotor 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 underwear is placed in the second washing tub 13.
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 are placed in washing tub 3.
Next, white items such as blouses and slips are placed in the second washing tub 13 and washed.

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. Second washing tub 13
The washing machine is easy to use and can shorten the washing time because it can wash the clothes in one go, whereas conventional washing machines without the washing machine wash the clothes twice.

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 this, water is poured into each of the washing tub 3 and the second washing tub 13 to a predetermined 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. Drainage of the second washing tub 13 is performed by removing the plug 21 of the drain hole 20.

Place colored or heavily soiled items in the second washing tub 1.
When washing in step 3, the second washing tub 13 is removed from the washing tub 3, carried to the drain, and the water to be washed is discarded. 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, 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 that have been washed separately other than colored items, a good way to use them is to remove the second washing tub 13, rinse them together in the washing tub 3, and dehydrate them 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.

The plug 21 of the second washing tub 13 is removed and water is poured into the second washing tub 13. Water does not accumulate in the second washing tub 13 and falls into the washing tub 3. Washing tub 3
After checking that the water has been poured to a predetermined level, plug the stopper 21 and close the drain hole 20.
Water can be stored in the second washing tub 13.

(2) When washing a small amount When washing a small amount or leaving unwashed items, use the second
A 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, the washing tub 3 with a large capacity
When washing only a small number of items, the amount of water used for washing cannot be reduced very much, resulting in a lot of wasted water and detergent.

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

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. Second
Since the washing tub 3 from which the 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 small quantities, and is easy to use as it can wash many items at once, just 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. The washing motor 7 is operated to perform washing. When you finish washing, do not throw away the washing water. The items to be washed with a white background are transferred to a dehydration tank 5, and the items to be washed with a red background are placed in a second washing tub 13. The dewatering motor 8 and the washing motor 7 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. Do not throw away the washing water,
After putting black items to be washed into the second washing tub 13, the dewatering motor 8 and washing motor 7 are operated to perform washing and dewatering in parallel. Wash, rinse. Dehydration work is being 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 items twice, so if there is a risk of damage to the fabric, rinse and wash the second time.
If you remove the washing tub 13, you will only have to wash it once.

Since the dehydration of the white laundry is the final dehydration, when the dehydration is completed, it is taken out of the dehydration tank 5 and transferred to a basket or the like in preparation 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 spin-drying, take out the black laundry items from the dehydration tank 5, move the rinsed red laundry items to the dehydration tank 5, put the black laundry items instead into the washing tub 13, and perform dehydration and rinsing at the same time. Let's do it. 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, washing by the second washing tub 13,
Dehydration in the dehydration tank 5, rinsing in the washing tank 3,
Washing water, detergent, and rinsing water can be saved by washing items with a white background that won't discolor first, and last with items with a black background that doesn't transfer easily, in the order of final dehydration in the dehydration tank 5. can be realized. 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-dispersed into the spin-drying tank 5, so there is less dirt in the rinsing water, and the volume of the washing tub 3 is larger than that of the second washing tub 13, which stores a large amount of rinsing water. Because you can. 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.
is formed. Dehydration outer tank 3 shown in Figure 1
3 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.

〔Effect of the invention〕

The present invention includes a small-capacity second washing tub that is placed inside the upper part of the washing tub, and a rotary blade that is rotatable at the inner bottom of the second washing tub. As the cleaning room is configured,
By attaching the second washing tub to the washing tub, a clutch is provided that connects the main rotor blade on the washing tub side and the rotor blade of the second washing tub, and a drain valve for draining water is installed at the bottom of the second washing tub. It is characterized by the fact that it has been provided.

According to this, there are the following advantages.

(1) The washing time can be shortened because the items to be washed can be placed in the washing tub and the second washing tub separately and washed at the same time.

(2) Small items to be washed or small items to be washed should be placed in the second category.
Since washing can be done using a washing tub, washing water and detergent can be saved.

(3) If you remove the second washing tub, you can wash more clothes at once in the washing tub.

(4) Since there is a drain valve at the bottom of the second washing tub, by opening this drain valve, water can be drained together with the washing tub, making it easy to drain water. If it is undesirable to drain water into the washing tub, make a second washing tub.
Carry it to the drain and throw away the water you want to wash. Since the second washing tub has a small capacity, it is easy to carry.
