Description

Clothes processing device {LAUNDRY TREATING APPARTUS}

The present disclosure relates to a laundry treatment apparatus, and more particularly, to a laundry treatment apparatus including a plurality of laundry treatment machines and a moving roller unit.

Washing machines, dryers, and refreshers that process clothes are placed in different spaces, such as kitchens, multipurpose rooms, living rooms, and outdoors, according to their uses within the living space.

Korean Patent Publication No. 10-2020-0109194 discloses a washing machine. The washing machine supplies water and detergent to a tub and a drum, and rotates a drum containing laundry to wash the laundry. The washing machine may supply water to the tub or drum through an external water source, circulate water in the tub to the drum, or discharge water in the tub to the outside using a pump. In general, a washing machine is placed in a kitchen or utility room for water supply and drainage.

A washing machine may separately include a heater for heating air, a blowing fan, and a steam generating device to dry or sterilize laundry.

Korean Registered Patent No. 10-2120993 discloses a dryer. The dryer heats air using a heating means and a blower fan and then supplies the air to the inside of the drum to dry the laundry accommodated inside the drum. In general, the dryer is disposed adjacent to the washing machine to dry the laundry after washing and to easily put the laundry containing moisture into the dryer.

Dryers can sterilize laundry or remove wrinkles from laundry by using a steam generating device that generates steam and sprays the generated steam into the drum. Water may be supplied into the dryer to generate the steam, and non-steamed water may be reused or discharged to the outside. In addition, a deodorizing function of filtering circulated air to remove the smell of laundry being dried may be added to the dryer.

Korean Registered Patent No. 10-2254903 discloses a refresher. The refresher supplies hot air and steam to a space where clothes are accommodated to dry, deodorize, remove wrinkles, remove static electricity, and/or sterilize clothes (hereinafter, also referred to as "refreshing").

The refresher is mainly used to manage clothes that users frequently use after washing, such as suits and coats. Generally, users hang clothes such as suits and coats in a closet to store them. Accordingly, unlike a washing machine, the refresher may be disposed adjacent to a closet or instead of a closet in a space such as a dressing room, living room, or bedroom. On the other hand, the refresher can perform laundry including not only clothes or clothes, but also objects that people can wear, such as shoes, socks, gloves, hats, scarves, etc., and objects that people frequently use, such as dolls, towels, and blankets. You can manage anything you have.

However, conventional clothes handlers disposed in different spaces have a problem in that a work flow is lengthened and clothes management is inconvenient because the clothes sorted by the user must be transported to each clothes processor that manages the corresponding clothes.

In addition, since the refresher is disposed in a space different from the washer and dryer, it is inconvenient to transport the washed wet clothes or dried clothes to the space where the refresher is placed.

In addition, in conventional laundry treatment machines that treat clothes using hot air and steam, each device separately includes a water supply facility, a drainage facility, an air heating device, a steam generator, a pump, a blowing fan, an air passage, and a steam passage. Therefore, there is a problem in that the clothing accommodating space becomes small. In addition, as each device separately includes a heating device and a steam generating device, there is a problem in that the cost and energy consumption of the entire system increase.

On the other hand, a conventional laundry handling apparatus having a plurality of laundry handling machines does not include a separate moving means, and thus, there is a problem in that it is cumbersome to move the laundry handling apparatus during initial installation or when changing an arrangement after installation.

The vertical extension plate 94d may be bent from the horizontal extension plate 94b and extended in the height direction so that the second roller unit 91' is disposed at the same height as the first roller unit 90. .

For example, the vertical extension plate 94d is vertically bent at the opposite end of the third fixing plate 94a among the ends of the horizontal extension plate 94b to the upper side of the height direction of the laundry treatment apparatus A'. It can be extended by a predetermined length.

At this time, the horizontal extension plate 94b adjusts the height of the fastening point of the bracket support leg 99, which is the point at which the weight of the laundry treatment apparatus A' is transferred from the horizontal extension plate 94b to the bracket support leg 99. In order to secure structural stability by lowering, the first roller unit 90 may be disposed lower than the height of the first horizontal plate 92b, which is fixed.

Therefore, the predetermined length is a length that overcomes the height difference between the horizontal extension plate 94b and the first horizontal plate 92b so that the first and second roller units 90 and 91' are disposed at the same height. can

Therefore, by the vertical extension plate 94d, the first and second roller units 90 and 91' are moved from the bottom surface F and/or the lower side of the support legs 97 and 99 to the same height, for example, by h. can be separated

At this time, the third rigid plate 94c may be orthogonal to the horizontal extension plate 94b and the third fixed plate 94a. At this time, the third rigid plate 94c may be integrally formed with the horizontal extension plate 94b and the third fixing plate 94a.

Therefore, the third rigid plate 94c supports the third fixing plate 94a and the horizontal extension plate 94b, thereby improving the rigidity of the third bracket 94 and tilting the laundry treatment device A' to remove the roller. In the rolling motion, the third bracket 94, the second roller unit 91', and the bracket support leg 99 transmit the third Deformation of the bracket 94 can be prevented.
