The present invention relates to a washing machine which prevents discoloration of the undergarment by the outer garment which may occur when the outer garment and the undergarment are washed together, and provides a more efficient washing stroke. More specifically, a large drum for washing a bulky outer garment and The present invention relates to a washing machine which is equipped with a small drum for washing a bulky underwear and can operate independently or in parallel according to a control signal of a controller.

As industrialization progressed and various machines were invented, washing machines to replace laundry have been developed for a long time, and the recent increase in the number of working couples has reduced the housewife's labor time and the spread of personal hygiene ideas to pursue a cleaner environment. As a result, many large-sized washing machines capable of washing quilts and bed covers, etc. have been developed and are widely used.

However, since the conventional washing machine has only one washing tank, when washing the outer garment and the underwear at the same time, it was inevitable to perform the washing by the method illustrated below.

(1) Wash your outerwear in the washing machine first, and then wash your underwear in the washing machine separately (2) Wash your underwear yourself (3) Install two washing machines to wash your underwear, or (4) The housewife could not but wash the clothes and underwear together in the washing machine.

However, in the case of (1), washing a small amount of bulky underwear which is changed into a large washing machine every day is not only a waste of energy and resources, but also a washing time of 2 to 4 hours in a soaking washing method is a small amount of laundry. It is inefficient to wash. To avoid this, it is necessary to wait for a large amount of underwear to be stored in a large washing machine. In this case, the odor and germ propagation from the laundry may harm the hygiene. In the case of (2), daily hand-washing of underwear such as panties that are worn every day and underwear like Maryas increases the housewife's fatigue, which is a big burden on housework. In addition, when hand-washing, we wash laundry by hand, so when it is placed on an indoor drying rack, unlike clothes dehydrated in a washing machine, water is dropped during the drying process, and the drying process takes a long time. In the case of (3), water pipes for washing machine installation are separately installed in apartments, but generally, only water pipes for one washing machine are buried, so when washing two underwears and outerwear with two washing machines, the water pipes are alternated in each washing machine. There is a problem to be connected. In addition, since only one water pipe can be used, it is impossible to simultaneously drive two washing machines. In the case of (4), if white clothes or garments with more pollution than underwear are washed with underwear, white underwear may be discolored by colored clothes, and underwear may be contaminated by outer clothes. Also, the bulky underwear may not be washed properly due to the bulky outerwear. In addition, when washing clothes together with underwear in a washing machine, to remove the underwear contaminated by the contaminants of the coat, the underwear is heated separately by heating or chemicals such as sodium percarbonate or sodium hypochlorite are added. After bleaching for a long time, it has to be washed several times.

As illustrated above, when using a washing machine equipped with a conventional washing tub, there is a problem in that washing cannot be performed by actively coping with various kinds of laundry.

The present invention has been made to solve the above problems, the present invention reduces the waste of water and power when washing a small volume of underwear, while reducing the contamination of underwear that can occur when washing outerwear and underwear at the same time, hands The purpose of the present invention is to provide a washing machine that can reduce the housewife's fatigue caused by laundry and reduce the washing time of the housewife.

The present invention devised in order to achieve the above object is the main body is formed with a first door for the small laundry input and a second door for large laundry input on one surface; A first tub for washing small laundry formed inside the first door; A second tub for washing large laundry that is formed inside the second door; A first drum formed inside the first tub and rotating about a rotation axis; A second drum formed inside the second tub and rotating about a rotation axis; A first motor connected to the rotating shaft of the first drum to impart rotational force to the drum; A second motor connected to the rotating shaft of the second drum to impart rotational force to the drum; A first water supply hose connected to the first drum to supply wash water to the first drum; A second water supply hose connected to the second drum to supply wash water to the second drum; A dispensing unit configured to connect the first water supply hose and the second water supply hose, and to mix and supply the washing water and the detergent flowing into the first drum and the second drum; And a connection hose interposed between the first drum and the second drum to supply washing water to the second drum via the first drum.
Preferably, it is formed in a predetermined portion of the first drum, and once discharged the wash water introduced into the first drum, the discharged wash water is introduced again to the first drum using the driving force of the circulation pump A first circulation hose forming the circulation passage may be formed.
In addition, it is formed in a predetermined portion of the second drum, and once discharged the wash water introduced into the second drum, the discharged wash water is introduced into the second drum again by using the driving force of the circulation pump flow path A second circulation hose may be formed.
