Description

The present invention relates to a laundry machine capable of washing or drying the laundry.
A washing machine is an electric home appliance washing capable of clothing, and a drying machine is an electric home appliance drying capable of wet clothing, etc. Recently, electric home appliances combining the functions of the washing machine and the drying machine have been widely used. Hereinafter, for the sake of explanatory convenience, the washing machine, the drying machine, and the electric home appliances combining the functions of thereof will be commonly called as a laundry machine.
The laundry machine is generally classified into a top loading type and a front loading type according to the position in which the laundry is put. And, the laundry machine is classified into a vertical axis type where a drum or a pulsator rotates and a horizontal axis type where a horizontally placed drum rotates, according to the manner performing the washing. A representative example of such a horizontal type is a drum laundry machine or a drum dryer.
The conventional laundry machine is generally directly installed on the bottom surface, wherein the inlet of the front loading type laundry machine is low so that it is inconvenient for a user to draw in and out the laundry. Therefore, it is requested that the height of the inlet of the laundry machine is more raised.
Generally, each home has one laundry machine. Therefore, when wishing to classify and wash the laundry according to the sorts thereof, the washing machine is used several times. For example, when wishing to wash the laundry by dividing it into the laundry such as adult clothing and the laundry such as underwears and baby clothing, etc., the washing machine is used again in order to wash the latter after the washing of the former is completed. Thereby, a lot of washing time is taken and a lot of energy is also consumed.
Also, in view of the energy saving, it is not preferable to use a large-sized laundry machine, as shown in the prior art when washing a small amount clothing. The washing course provided in the large-sized laundry machine generally expects the case with a lot of washing water so that a lot of water is consumed. And, a lot of power is consumed for rotating a large-sized drum or a pulsator.
Also, since the washing course expects a large amount laundry, the washing time is comparatively long. And, the large-sized laundry machine is provided with the washing course expecting mainly general clothing, so that it may not be suitable for washing delicate cloth such as underwears or baby clothing.
And, even in the case where a small amount laundry is frequently washed, the large-sized washing machine is not suitable. A consumer gathers the laundry over several days or more in order to wash it at a time.
It is not good for underwears and baby clothing, etc. to be left for a long time in view of sanitation. And, if such laundry is left for a long time, dirt is clung to cloth to causes a problem that it is not cleanly washed.
Therefore, the necessity of a small-sized laundry machine having much smaller capacity than the conventional large-sized laundry machine has increased. However, despite the small-size laundry machine, it is not preferable to provide two laundry machines in one home in view of the space utilization, and it is not good either in appearance. In WO 2008/069607 , a complex washing machine including an auxiliary washing machine capable of serving as a pedestal for a main laundry machine is disclosed.
It is an object of the present invention to provide a laundry machine having a high positioned laundry inlet for improving the convenience thereof and comprising at least one washing tub.

Hereinafter, the embodiments of the present invention which can carry out the technical solutions as above will be described in detail with reference to the accompanying drawings.
FIGS. 1 and 2 are views showing one embodiment of a laundry machine according to the present invention.
The laundry machine 1 according to the present invention comprises a cabinet 110 forming an outer appearance, and a first washing tub 120 provided in the cabinet 110.
The cabinet 110 comprises a front cover 111 forming a front, side walls forming both side surfaces, a rear wall 114 forming a rear surface, and a top plate 116 forming a top surface.
The front cover 112 of the cabinet 110 is provided with a door 140, and the front upper of the cabinet 110 is provided with a control panel 119 to allow a user to operate the laundry machine 1.
And, the first washing tub 120 comprises a first tub 122 storing washing water and a first drum 124 rotatably disposed in the first tub 122.
The first tub 122 and the first drum 124 are formed to have an opening part formed to be connected to the external for drawing in and out the laundry when the door 140 is opened. Also, the first drum 124 rotates by a motor 130, and the inner surface thereof is provided with a number of lifts 126 to perform the washing in the manner of lifting up and dropping the laundry inside the drum when the drum rotates.
Meanwhile, the opening part may not be formed at the front of the cabinet but at the upper side thereof, and the first washing tub may be formed in a shape not to lie down but to stand against the ground.
Meanwhile, when the door 140 of the laundry machine 1 is formed in the front surface of the cabinet 110, a user should bend his/her body to draw in and out the laundry into the inside of the first washing tub 120. Therefore, in order to prevent the user from excessively bending his/her body, it is requested that the washing tub 120 is positioned above a predetermined height.
To this end, as shown in FIGS. 1 and 2, a case 200 lifting up the height of the first washing tub to a predetermined height may be installed under the laundry machine 1.
The case 200 may be formed to have a predetermined height so that the cabinet of the laundry machine 1 may be raised to the upper side.
Also, the case 200 may be formed to have a predetermined space in the inside thereof and to receive the laundry supplies in the space for efficiently using the space.
Also, in order for the user to conveniently draw in and out things inside the case 200, the inside of the case 200 has a predetermined space capable of receiving supplies and may be further provided with a housing 210 formed to be able to be drawn in and out and received from the space of the case 200.
Also, the case 200 as above may be installed in the lower of the cabinet 110, and may be installed in the upper side or the side portion thereof, as needed, although not shown in the drawings.
And, a second washing tub 220 capable of receiving the laundry separately from the first washing tub 120 and then performing the washing may be disposed in the housing 210.
The first and the second washing tub 220 may be formed to be operable by the common controller 119 provided in the cabinet 110.
The second washing tub 220 is operable independently from the first washing tub 120, and can comprise a second tub receiving washing water and a second drum rotatably disposed in the second tub. Also, it may be formed of the second tub receiving the washing water and a second drum rotatably disposed in the second tub. Also, it may be formed of a pulsator rotatably provided in the second tub receiving the washing water. Other washing tubs in various manners not described in the present specification may be provided.
Therefore, as the second washing tub 220 is provided separately from the first washing stub 120, the washing can be promptly performed by selecting a proper washing tub depending on the amount of the laundry, without the waste of washing water and energy.
Also, as the first washing tub 120 and the second washing tub 220 each are separately provided to be able to independently operate to each other, they may be formed to have different washing manner, and a user can select and use a more proper washing tub according to the kinds and characteristics of the laundry, making it possible to improve washing efficiency and reduce the cloth damage of the laundry.
Also, dark colored clothes and light colored clothes should be separated and washed in order to prevent them from dyeing. In this case, the first washing tub 120 and the second washing tub 220 are separated so that the washing can be performed at a time without washing twice, making it possible to reduce washing time.
The second washing tub 220 is received in the housing 210, and a vibration may be generated depending on eccentricity of the inside laundry when the second washing tub 220 rotates. Although not shown, it is suspended to the inside of the housing 210 in order to reduce the vibration.
Therefore, the second washing tub 220 may be vibrated in the housing 210 by means of its own vibration and may be also vibrated by means of an external force applied to from the external during a transportation of the laundry machine.
Generally, the suspension apparatus supporting the second washing tub 220 is designed not to contact the second washing tub 220 to the wall surface of the housing 210 to prevent the vibration generated from the second washing tub 220 itself during the operation thereof. However, the suspension apparatus is hard to cope with the vibration of the second washing tub 220 due to the external force so that the second tub 220 is greatly shaken in the housing 210. As a result, there is a risk that the second washing tub 220 may be collided with the wall surface of the housing or the parts thereof may be damaged. Such an external force may be mainly generated during the movement of the laundry machine.
Also, as the housing 210 is unexpectedly drawn out during the movement of the laundry machine, a person moving the laundry machine may be hurt, the laundry machine may be damaged due to the collision with other things, or the laundry machine may be damaged due to the impact caused when the housing is drawn out.
Therefore, according to the present invention a fixing member 250 capable of fixing the housing 210 or the second washing tub 220 during the movement of the laundry machine is provided.
