The present disclosure relates to a laundry treating apparatus including a duct for supplying air.
Laundry treating machines, such as washing machines, dryers, and refreshers, are installed in different spaces, such as a kitchen, a utility room, a living room, and an outdoor space, according to usage in a residential space.
Korean Patent Publication of 10-2020-0109194 A discloses a washing machine. The washing machine washes laundry by supplying water and detergent into a tub and a drum and by rotating the drum in which the laundry is placed. In the washing machine, water from an external water source is supplied into the tub or the drum, and a pump is used to circulate the water in the tub to the drum or to discharge the water in the tub to the outside. The washing machine is generally installed in the kitchen or the utility room for supplying and discharging water.
The washing machine separately includes a heater for heating air, a blower fan, and a steam generator, to dry or sterilize the laundry.
Korean Patent No. 10-2120993 B discloses a dryer. The dryer may dry the laundry, placed in the drum, by heating air using a heating means and a blower fan and by supplying the heated air into the drum. The dryer is generally disposed adjacent to the washing machine, so as to dry the washed laundry and to allow a user to easily put the laundry containing moisture into the dryer.
By using the steam generator for generating steam and spraying the steam into the drum, the dryer may sterilize the laundry or may relieve wrinkles from the laundry. Water may be supplied into the dryer for generating the steam, and water not converted into steam may be reused or may be discharged to the outside. Further, in order to deodorize the dried laundry, the dryer may further have a deodorization function for filtering the circulated air.
Korean Patent No. 10-2254903 B discloses a refresher. The refresher may have functions, such as drying, deodorizing, de-wrinkling, de-static and/or sterilization (hereinafter referred to as “refreshing”).
The refresher is used for treating clothes, such as suits and coats, which are frequently used by a user after washing. Generally, the user hangs the clothes, such as suits and coats, in a wardrobe. Accordingly, the refresher may be installed adjacent to the wardrobe, or may be installed instead of the wardrobe, in a dressing room, a living room, or a bedroom. Further, not only for the clothes or garments, the refresher may also be used for all washable items, such as shoes, socks, gloves, hats, scarves, etc., which are worn by users, as well as dolls, towels, blankets, etc., which are frequently used by users.
However, the existing laundry treating machines, which are installed in different spaces, have a problem in that users need to move the laundry items, which are sorted by the user, to the respective laundry treating machines performing corresponding laundry treating processes, thereby requiring a longer workflow, and making the laundry treating processes uncomfortable.
In addition, as the refresher is installed in a different place from the washing machine and the dryer, it is cumbersome for users to move the washed wet laundry or the dried laundry to the place where the refresher is installed.
Furthermore, each of the existing laundry treating machines for treating the laundry using hot air and steam separately requires water supply equipment, drainage equipment, an air heater, a steam generator, a pump, a blower fan, an air passage, a steam passage, etc., thereby causing a problem in that a space for receiving clothes is reduced. In addition, each of the machines includes the heater, the steam generator, etc., thereby increasing costs and energy consumption of the entire system.
It is an object of the present disclosure to solve the above and other problems.
It is another object of the present disclosure to provide a laundry treating apparatus including a plurality of laundry treating machines.

Hereinafter, a method of controlling a blowing direction of air by the switching device 70 will be described with reference to
The fan 60 may be a sirocco fan. The fan 60 may rotate to blow air in a direction perpendicular to the rotating shaft 61. The fan 60 may blow air in a direction coming into contact with the rotation direction. The air blown by the fan 60 may be concentrated in a predetermined range of angles relative to the rotating shaft 61.
The fan 60 may include the rotating shaft 61 coupled to the fan motor and rotated thereby, a plurality of blades 62 spaced apart in a radially outward direction of the rotating shaft 61, and an outer body 63 coupled to the blades 62 and extending in a rotation direction of the fan 60. The outer body 63 may have an annular shape. The rotating shaft 61 and the blades 62 may be connected by the outer body 63. When the rotating shaft 61 rotates, the outer body 63 and the blades 62 may also be rotated together with the rotating shaft 61.
The rotating body 71 may include a rotating plate 71a having the driven gear 713, a scroll 71b coupled to the rotating plate 71a, and a shaft through hole 71c formed in the rotating plate 71a.
The rotating plate 71a may have a disk shape and may be disposed in the rear of the fan 60. The driven gear 713 may be formed in an annular shape on one side surface of the rotating plate 71a. The driven gear 713 may be integrally formed with the rotating plate 71a. When the driven gear 713 is rotated in engagement with the driving gear 711, the rotating plate 71a may be rotated in the same direction as the rotation direction of the fan 60. The rotating plate 71a may have the shaft through hole 71c, through which the rotating shaft 61 passes. The rotating shaft 61 may pass through the shaft through hole 71c to be coupled to the fan motor.
The fan 60 may be disposed between the heat exchange channel 24 and the rotating plate 71a. That is, the rotating plate 71a may be disposed behind the heat exchange channel 42 and the fan 60. The rotating plate 71a may be disposed behind the fan 60 in the blowing duct 420.
