Description

Apparatus for treating clothes {Laundry Machine}

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 achieve the above object, the present invention provides a washing machine comprising: a first washing tub for containing laundry; A housing disposed adjacent to the first washing tub and installed to be drawn out to the outside; A second washing tub provided inside the housing for receiving laundry; And a support member for supporting the second washing tub against the housing and elastically damping vibration of the second washing tub.

The support member may limit the displacement of the second washing tank to a predetermined width.

The housing may be housed in the space of the case or may be detachably installed in the case.

The support member may be respectively coupled to a first portion that is a portion that vibrates integrally with the second washing tub and a second portion that is a portion that vibrates integrally with the housing.

Wherein the support member is made of a rigid material and is provided between the first portion and the second portion to substantially support the second washing tub; And a bushing provided between the supporting bar and the first and second parts, respectively, for attenuating vibrations transmitted from the second washing tub.

The bushing is provided at both ends of the support bar and can be supported by the support bar.

The bushing may have a hole for engaging with the support bar and a groove for engaging the first and second parts.

The first portion may include an upper bracket extending from the second washing tub, and the second portion may include a lower bracket extending from the housing.

The upper bracket and the lower bracket may be formed with holes for engaging with the bushing.

The support member may be provided outside the outer circumferential surface of the second washing tub.

And a spring for elastically supporting the left and right vibrations of the second washing tub.

One end of the spring may be coupled to a first portion that is a portion that vibrates integrally with the second washing tub, and the other end may be coupled to a second portion that is a portion that vibrates integrally with the housing.

One end of the spring may be coupled to the support member, and the other end may be coupled to the second portion, which is a portion vibrating integrally with the housing.

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 second washing tank disposed in the narrow space can reduce the displacement caused by its own load to a minimum, thereby improving the space utilization. By limiting the vibration displacement width and damping the vibration by a simple structure, So that the size of the washing tub can be maximized.

Hereinafter, embodiments of the present invention in which the above-mentioned problem solution can be specifically realized will be described with reference to the accompanying drawings.

1 and 2 are views showing an embodiment of a clothes processing apparatus according to the present invention.

The clothes processing apparatus 1 according to the present invention may include a cabinet 110 forming an outer appearance and a first washing tub 120 installed inside the cabinet 110. [

The cabinet 110 includes a front cover 112, a front wall 112, a rear wall 114, and a top plate 116.

A door 140 is provided on the front cover 112 of the cabinet 110 and a control panel 119 for operating the laundry processing apparatus 1 is provided on the front of the cabinet 110 Respectively.

The first washing tub 120 may include a first tub 122 for 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 formed to communicate with the outside for drawing out laundry when the door 140 is opened. In addition, the first drum 124 is rotated by the motor 130, and a plurality of lifts 126 are provided on the inner surface thereof, thereby washing the laundry in the drum while lifting and dropping the laundry in the drum.

The opening may be formed not to face the front surface of the cabinet but may be directed upward, or may be formed on the ground instead of the first washing tub.

When the door 140 of the laundry processing apparatus 1 is formed on the front surface of the cabinet 110, the user must bend his or her back in order to insert or remove the laundry into the first washing tub 120. Therefore, in order to prevent the user from excessively bending the waist, the washing tub 120 needs to be positioned at a predetermined height or more.

For this purpose, as shown in FIGS. 1 and 2, a case 200 for raising the height of the first washing tub to a predetermined height may be installed under the clothes processing apparatus 1.

The case 200 may be formed to have a predetermined height so as to raise the cabinet of the clothes processing apparatus 1 to the upper side.

In addition, the case 200 is formed to have a predetermined space therein, and the laundry can be stored in the space so that the space can be efficiently used.

In addition, the case 200 has a predetermined space in which the article can be stored, so that the user can conveniently insert and remove the article from the case 200, The housing 210 may be further formed with a plurality of protrusions.

In addition, the case 200 may be installed at a lower portion of the cabinet 110, or may be located at an upper side or a side portion, if necessary, although not shown in the drawing.

The housing 210 may be provided inside the case 200 separate from the cabinet 110 housing the first washing tub 120 as described above, Or may be provided inside the cabinet 110 to be integrated with the cabinet 110, as shown in FIG.

The housing 210 is detachably disposed in the cabinet 110 and may be disposed below the first washing tub 120.

The housing 210 may be provided inside the cabinet 110 and may be provided inside the case 200 to secure a predetermined space for housing the housing 210.

A second washing tub 220 may be disposed in the housing 210 to receive laundry and wash the washing tub 120 separately from the first washing tub 120.

The second washing tub 220 can be operated by a control unit 119 provided in the cabinet 110.

The second washing tub 220 may operate independently of the first washing tub 120 and may include a second tub which receives the washing water and a second drum rotatably disposed in the second tub . Or a pulsator rotatably installed in a second tub for receiving wash water, or may be provided with various types of washing machines not described in the present description.

Accordingly, the second washing tub 220 is separately provided separately from the first washing tub 120, so that it is possible to select a suitable washing tub according to the amount of the laundry and quickly wash the laundry without wasting the washing water or energy.

Since the first washing tub 120 and the second washing tub 220 are separately provided, they can be operated independently of each other, so that they can have different washing methods, and the user can be more suitable according to the type and nature of the laundry A washing tub can be selected and used, thereby improving the washing efficiency and reducing the bodily damage of the laundry.

Since the first washing tub 120 and the second washing tub 220 are separate from each other, it is possible to carry out the laundry without having to double the laundry. And the washing time is shortened.

Meanwhile, the housing 210 provided inside the case 200 is generally formed not to have a high height for practical use. That is, if the height of the case 200 is too high, if the case 200 is provided below the first washing tub 120, the opening of the first washing tub 120 may be positioned too high If the case 200 is provided on the upper portion of the first washing tub, the height of the second washing tub 220 may be excessively high, and the user's comfort may be deteriorated.

Therefore, it is preferable that the height of the housing 210 is not too high. In addition, it is preferable that the supporting member 210 can efficiently support the second washing tank 220 in a limited space inside the housing 210, (230) may be provided.

Generally, the support and attenuation of the washing tub is made by a suspension device made of a cylinder, a piston, a spring, a damper, and the like, which are stretchable and extendable. It is disadvantageous to be used for supporting the second washing tub 220 provided inside the housing 210 having a very small height and width.

Therefore, the support member 230 for supporting the second washing tub 220 provided inside the housing 210 of the present invention and damping the vibration suppresses the second washing tub 220 from being lowered by the load as much as possible , And the displacement caused by the vibration of the second washing tub 220 is limited within a predetermined width.

The support member 230 may be coupled to a portion vibrating integrally with the second washing tub 220 and a portion vibrating integrally with the housing 210.

Hereinafter, a portion vibrating integrally with the second washing tub 220 will be referred to as a first portion 222, and a portion vibrating integrally with the housing 210 will be referred to as a second portion 212.

That is, the support member 230 is provided between the first portion 222 and the second portion 212 and is coupled to the first portion 222 and the second portion 212, respectively.

The support member 230 may include a support bar 232 that substantially supports the second washing tub 220 with respect to the housing 210 and a bushing 250 that attenuates vibration transmitted from the second washing tub 220 234).

The support bar 232 may be substantially rigid to prevent the second washing tub 220 from falling due to its weight. That is, the support bar 232 does not extend or contract.

The bushing 234 may be made of rubber or the like having appropriate elasticity and rigidity for absorbing vibrations and the support bar 232 and the first and second parts 222 and 212 And may be provided between the engaging portions.

That is, the bushing 234 is coupled to both ends of the support bar 232, and the bushing 234 is coupled to the first portion 222 and the second portion 212, respectively.

The first part 222 may include an upper bracket 224 extending from the second washing tub 220 and vibrating integrally with the second washing tub 220, And a lower bracket 214 extending from the housing 210 and moving integrally with the housing 210.

Accordingly, the bushing 234 is coupled to the upper bracket 224 and the lower bracket 214, respectively.

Of course, the first part 222 and the second part 212 are not limited to the upper bracket 224 and the lower bracket 214 but may be connected to the second washing tub 220 and the housing 210 itself .

That is, the bushing 234 may be coupled to the upper bracket 224 and the lower bracket 214, or may be directly coupled to the second washing tub 220 and the housing 210.

5 is a view showing a relationship in which the upper bracket 224, the bushing 234, and the support bar 232 are engaged.

The upper bracket 224 is formed with a hole 226 for engaging with the bushing 234. A groove 236 is formed on the outer circumferential surface of the bushing 234 to be engaged with the hole 226 of the upper bracket 224.

A pin 233 for insertion into the bushing 234 is formed at the end of the support bar 232 and a hole 233 for receiving the pin 233 of the support bar 232 is formed in the bushing 234. (235) are formed.

That is, the pin 233 passes through the hole of the bushing 234 to couple the bushing 234 and the support bar 232 to each other, and the inner peripheral surface of the hole 235 of the upper bracket 224 and the inner peripheral surface of the bushing 234 The bushing 234 is coupled to the upper bracket 224 by engaging a groove 236 formed on the outer circumferential surface of the upper bracket 224.

The diameter of the support bar 232 is preferably larger than the diameter of the bushing 234. This is because the support bar 232 supports the bushing 234 more reliably.

The coupling between the bushing 234 coupled to the bushing 234 and the lower bracket 214 and the lower bracket 214 and the support bar 232 are also similar to those described above, Therefore, detailed explanation will be omitted.

6 is a view showing a support member when the second washing tank vibrates.

When washing water or laundry is put into the second washing tub 220, the weight of the laundry is increased. At this time, the bushing 234 of the support member 230 supporting the second washing tank 220 is slightly compressed and the second washing tank 220 can be lowered. Since the support bar 232 is made of a rigid body, the supporting bar 232 itself is not deformed. Therefore, the distance that the second washing tub 220 descends is limited to the amount of deformation of the bushing 234.

When the second washing tub 220 is vibrated, the supporting bar 232 is tilted to the left or right according to the amount of displacement of the second washing tub 220. The support bar 232 is not deformed and the bushing 234 coupled to the support bar 232 and the first and second portions 222 and 212 is deformed to absorb and attenuate vibration .

That is, the second washing tub 220 is supported by the supporting member 230, and the vibration of the second washing tub 220 is attenuated by the supporting member 230.

The width and vibration amount of the vibration displacement of the second washing tub 220 can be determined by the length of the supporting bar 232 and the rigidity of the bushing 234 and the like, A description thereof will be omitted.

Further, a spring for elastically supporting the left and right vibrations of the second washing tub 220 may be further provided.

7 is a view showing a state where a spring 240 is provided in the second washing tub 220 of the clothes processing apparatus of the present invention.

One end of the spring 240 is coupled to the first portion 222 vibrating integrally with the second washing tub 220 and the other end is connected to the second portion 212 moving integrally with the housing 210 Respectively.

That is, one end of the spring 240 may be coupled to the upper bracket 224 directly coupled to the second washing tub 220 or vibrating integrally with the second washing tub 220, The lower end of the housing 210 may be coupled to the lower bracket 214 directly coupled to the housing 210 or moving integrally with the housing 210.

Therefore, the vibration of the second washing tub 220 can be more effectively attenuated by the spring 240 elastically supporting the left and right vibrations of the second washing tub 220. [

Of course, it is also possible to replace the spring 240 with a member having elasticity or other elasticity.

It will be apparent to those of ordinary skill in the art of the present invention that the present invention may be embodied in many other forms without departing from the spirit and scope of the invention, Accordingly, the above-described embodiments are to be considered illustrative and not restrictive, and all embodiments within the scope of the appended claims and their equivalents are intended to be included within the scope of the present invention.
