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. I have to run the washing machine twice because I wash white items first, 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, water and detergent tend to be wasted when the amount of laundry is extremely small compared to the standard amount of laundry.

[Problem that the invention seeks to solve]

The object of the present invention is to provide a product that can wash the same amount of laundry without having to wash it twice, saves water and detergent, and can easily treat wastewater 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 rotor blades on the washing tub side and the rotary wings on the second washing tub side, and A drain valve is provided at the bottom for draining water.

Thereby, the above objective can be achieved.

[Effect]

By attaching the second washing tub to the washing tub, you can create two separate washing chambers divided into upper and lower sections, so you can separate the items you want to wash into the second washing tub and the washing tub, and wash them at the same time. be able to.

A small amount of laundry can be washed in the second small-capacity washing tub. Since the second washing tub is provided with a drain valve, by opening this drain valve, water can be drained together with the washing tub. When it is difficult to drain water into the washing tub, the second washing tub is carried around and the water to be washed is dumped 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 has an outer frame 1 made of steel plate,
A base 2 made of synthetic resin on which this outer frame is placed, a washing tub 3 made of synthetic resin housed within the outer frame 1, and a water tank formed integrally with the washing tub 3 and housed within the outer frame 1. A water receiving tank 4, a dehydrating tank 5 housed in the water receiving tank 4, a main rotary blade 6 provided at the center of the bottom of the washing tub 3, a washing motor 7 serving as a driving source for the main rotary blade 6, and a dehydrating tank 5 housed in the water receiving tank 4. A dehydration motor 8 serving as a driving source,
An operation panel box 9 is 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 drainage.

The main rotor 6 includes a disk-shaped wing body 10, a protrusion 11 projecting above the center of the wing body 10, and a cap body 12 attached to the tip of the protrusion 11. Cap body 12
A magnet with strong magnetic force is installed inside with an insert, etc.

A small-capacity second washing tub 13 , which 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. This second washing tub 13 is
As shown in FIG. 2, a rotor blade 14 is provided at the inner bottom of the tank, and this rotor blade 14 is 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 has drain hole 20
and a plug 21 that can be attached to and removed 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 6 and the rotor 14 are connected via the clutch, and the rotation of the main rotor Xi 6 is transmitted to the rotor 14. . By removing the second washing tub 13 from the upper side of the washing tub 3, the clutch is released.

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

(1) - When washing items separately ■Wash thin and thick items, colored items and white items, heavily soiled items and normally soiled items, small and medium sized items and large items, etc.

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, blouses, etc.
White items such as 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 blankets, 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 as many items as you want depending on the type of items you want to wash at once. Since the conventional washing machine without the second washing tub 13 can wash the clothes twice, it can be done in one wash, so the washing time can be shortened and the washing machine is easy to use.

■Washing tub 3. The washing operation from loading the items to be washed into 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 adding detergent.

A second washing tub 13 is set on top of the washing tub 3, and items to be washed and detergent are placed in this washing tub 13 in this order. When the laundry items to be washed are selected in advance and placed in the second washing tub 13, detergent may be placed in a trough set on top of 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.

After that, 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 1
4 rotate together. In this way, the washing tub 3 and the second washing tub 1
Three parts are washed at the same time.

■Drain the water after washing.

Normally, you should remove colored or heavily soiled items from the washing tub 3 below.
Therefore, there is no problem even if the washing water from the second washing tub 13 is dropped into the washing tub 3 and drained together with the washing water from the washing tub 3. The drain of the second washing tub 13 is drained from the plug 2 of the drain hole 20.
Do this by removing 1.

When colored or heavily soiled items are washed in the second washing tub 13, the second washing tub 13 is removed from the washing tub 3, carried to the drain, and the water to be washed is thrown away.

Since the second washing tub 13 has a small capacity, it is lightweight.

It is 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 water.

The items to be washed are taken out of the second washing tub 13 and placed in the dehydration tub 5. Remove the second washing tub 13 and insert the second washing tub 1 into the dehydration tub 5.
You may also drop the items to be washed in step 3.

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 that have been washed other than colored items, a good way to use them is to remove the second washing tub (13) and rinse them together in the washing tub (3) and spin them all at once.

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

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

Unplug the stopper 21 of the second washing tub 13, and
Pour water into. Water does not accumulate in the second washing tub 13, and the washing tub 3
fall into. 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) In the case of washing a small amount When washing unwashed items or washing a small amount, use the second washing tub 13.
Use. 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, just because there are few things to wash, if you use too little water to wash them, the washing will not be done 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, 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.

If you rinse with plenty of water, it will rinse well and the time for rinsing will be shorter. When such rinsing is desired, a washing tub 3 with a large capacity is used.

(3) When washing a large amount When washing a large amount at once, the second washing tub 13 is removed and the washing tub 3 is used. Since the washing tub 3 from which the second washing tub 13 is removed can be used up to the entire top, a large amount of laundry can be washed at once, like a normal washing machine. 'In this way, this washing machine can wash many 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, just like a normal washing machine. be.

(4) When washing three or more 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 washing is finished, the water to be washed is not thrown away, and the white items to be washed are transferred to the dehydration tank 5, and the red items to be washed are placed in the second washing tank 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 fresh water into the washing tub 3. Doing this while washing will save time. 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. 2nd washing tub 1 where you can keep the water you want to wash without throwing it away
After putting black items to be washed into the container 3, the dehydration motor 8 and the washing motor 7 are operated to perform washing and dehydration 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.

Transfer the rinsed white items to the dehydration tank 5, and instead transfer the red items to the washing tank 3, dehydrate and wash them.
Perform rinsing in parallel. How to wash black clothes 2
If there is a risk of damage to the cloth, rinse it and remove the second washing tub 13, so that you will have to wash it - times.

Since the dehydration of the white laundry is the final dehydration, once 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 first 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 into the city where the black laundry items can be 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, the three types of food can be washed.

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. You can save washing water, detergent, and rinsing water by washing items with a black background that does not transfer easily. 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 larger than that of the second washing tub 13, so it can store more rinsing water. It is from. 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, the water flows out from the slit 19, and the water level in the second washing tub 13 reaches the slit 19.
Fall inside.

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.

In the second washing tub 13 shown in FIG. 3, an overflow water conduit 32 is formed in a part of the upper edge flange portion 31 with a tub-shaped recess. 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.
