Description

[0001]

The present invention relates to a clothes processing apparatus capable of washing or drying clothes.

The washing machine is an appliance for washing clothes and the like, and the dryer is a household appliance for drying wet clothes. In recent years, home appliances having combined functions of a washing machine and a dryer have been widely used. Hereinafter, for the sake of convenience of explanation, a household appliance including a washing machine, a dryer, and a combination of these functions is collectively referred to as a clothes processing apparatus.

Generally, the clothes processing apparatus is divided into a top loading method and a front loading method depending on a laundry loading position. There is a vertical type in which the drum or pulsator rotates depending on the manner of washing, and a horizontal type in which the drum lies horizontally. A representative example of such a horizontal type is a drum washing machine or drum dryer.

Conventional clothes processing apparatuses are generally installed directly on the floor surface. Since the front loading type clothes processing apparatus has a low entrance, it is inconvenient for a user to insert and remove laundry. Therefore, there is a need to increase the height of the entrance of the clothes processing apparatus.

Generally, each household is equipped with one garment disposal device.

Therefore, when the laundry is divided according to the type of the laundry, the washing machine is used several times. For example, in the case of washing laundry such as adult clothes and laundry such as underwear or baby clothes, after the washing of the electronic is completed, the washing machine is used again for the latter washing. As a result, the washing time is long and the energy consumed is also large.

Further, it is not preferable from the viewpoint of energy saving to use a conventional large-sized clothes processing apparatus for washing a small amount of clothes. The laundry course provided in the large-sized clothes processing apparatus is predominantly in the case of a large amount of laundry, so the amount of water consumed is large. Further, a large amount of power is consumed because a large drum or pulsator must be rotated.

Also, since the laundry course is intended for mass laundry, the washing time is relatively long. In addition, since the large-sized clothes processing apparatus is provided with a laundry course predominantly for general clothes, it may not be suitable for washing delicate clothes such as underwear or baby clothes.

Even if a small amount of laundry is frequently washed, a large washing machine is not suitable. Consumers collect laundry for a few days or longer to collect the laundry at once.

Underwear and baby clothes are not good for long-term cleanliness. When the laundry is left for a long time, the laundry is stuck to the cloth and the laundry is not cleaned.

Thus, there is a growing need for a small-sized clothes processing apparatus that has a capacity much smaller than that of a conventional large-sized clothes processing apparatus. However, even if it is small, it is not preferable to use two clothes processing apparatuses in a single home, which is not preferable for space utilization, and is not good for aesthetic appearance.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a clothes processing apparatus having at least one or more washing tubs with increased convenience due to a high position of a laundry loading port of the clothes processing apparatus.

In order to solve the above-described problems, the present invention provides a washing machine comprising: a first washing tub disposed in a cabinet for receiving laundry; A case disposed adjacent to the first washing tub and having a predetermined space therein; A housing accommodated in the space of the case or installed to be withdrawn from the case; A second washing tub provided in the housing and receiving laundry separately from the first washing tub; And a driving unit selectively pulling the housing out of the case.

The driving unit may be provided between a rear surface of the housing and a rear surface of the housing and an inner rear surface of a case facing the driving unit.

The driving unit may be a push-in push-out system in which the housing is fixed in a state in which the housing is housed in the case and pushes the housing by elasticity when the housing is pressed again in a fixed state .

Alternatively, the driving unit may include: a spring for applying an elastic force in a direction of pulling out the housing; And a hook for selectively fixing the housing housed inside the case.

Further, a locking part for selectively fixing the housing housed in the case may be further provided.

The locking portion may include a hook for selectively restraining or releasing the housing.

Alternatively, the locking portion may include a solenoid for selectively restraining or releasing the housing.

The locking unit may restrict the housing so that the housing is not drawn out of the case when the second washing tub is rotating.

The damper may further include a damper for preventing noise when the housing is separated from the driving unit when the housing is drawn out of the case and the driving unit contacts the housing when the housing is housed in the case.

According to the clothes processing apparatus of the present invention, the following effects are obtained.

First, since the height of the first washing tub of the clothes processing apparatus is increased, the user does not have to swallow the excessive amount of laundry when the laundry is put into the first washing tub or taken out from the first washing tub.

Secondly, by providing a small-capacity second washing tub near the first washing tub, the user can select a washing tub suitable for the amount of laundry, thereby reducing unnecessary washing water and waste of energy.

Third, the second washing tank may be configured to use a washing method different from that of the first washing tub, and a washing method suitable for the type of laundry may be selected.

Fourth, the movable body having a relatively heavy weight equipped with the second washing tub can be easily taken out, thereby improving the convenience of the user.

Fifth, when the second washing tub is in operation, the locking part prevents the moving object from being drawn out, thereby improving the safety of the user.
