Abstract

Laundry treating equipment comprises a first laundry treating apparatus and a drying system. The first laundry treating apparatus includes a first laundry treating drum. The drying system includes a driving apparatus driving the first laundry treating drum to rotate, a drying component used for producing a drying airflow, and a drying airflow circulating apparatus being driven by the driving apparatus. The drying airflow circulating apparatus is used for delivering the drying airflow into the first laundry treating drum. The driving apparatus is connected to the first laundry treating drum via a clutch apparatus so as to selectively rotate with the first laundry treating drum. With the described structure provided, the laundry treating equipment allows a drying drum to rotate or be stationary via the clutch apparatus, thus facilitating the sharing of the drying system.

Claims

exact text as granted — not AI-modified
1 - 12 . (canceled) 
     
     
         13 . A laundry treatment apparatus, comprising:
 a first laundry treatment device and a drying system, wherein the first laundry treatment device comprises a first laundry treatment cylinder, the drying system comprises a driving device configured to drive the first laundry treatment cylinder to rotate, a drying assembly configured to generate a drying airflow, and a drying airflow circulation device driven by the driving device; the drying airflow circulation device is configured to deliver the drying airflow generated by the drying assembly into the first laundry treatment cylinder, and   wherein the driving device is connected to the first laundry treatment cylinder through an engagement device to selectively drive the first laundry treatment cylinder to rotate.   
     
     
         14 . The laundry treatment apparatus according to  claim 13 , further comprising a second laundry treatment device comprising a second laundry treatment cylinder, and the drying system is configured to be also capable of delivering the drying airflow generated by the drying assembly into the second laundry treatment cylinder. 
     
     
         15 . The laundry treatment apparatus according to  claim 14 , wherein the drying system further comprises:
 a first air inlet duct and a first air outlet duct in communication with an inner cavity of the first laundry treatment cylinder, respectively;   a second air inlet duct and a second air outlet duct in communication with an inner cavity of the second laundry treatment cylinder, respectively;   a drying air duct comprising an air inlet end and an air outlet end, the air inlet end being connected with the first air outlet duct and the second air outlet duct, and the air outlet end being connected with the first air inlet duct and the second air inlet duct; and   a switching device, wherein the air inlet end of the drying air duct is capable of selectively communicating with the first air outlet duct or the second air outlet duct through the switching device, and the air outlet end of the drying air duct is capable of selectively communicating with the first air inlet duct or the second air inlet duct through the switching device.   
     
     
         16 . The laundry treatment apparatus according to  claim 15 , wherein the drying assembly is disposed in the drying air duct, and the drying airflow circulation device is capable of directing the drying airflow to circulate in each of the air ducts. 
     
     
         17 . The laundry treatment apparatus according to  claim 16 , wherein the drying airflow circulation device is disposed in the drying air duct. 
     
     
         18 . The laundry treatment apparatus according to  claim 17 , wherein the drying assembly comprises a heating device configured to generate a drying airflow, and a condensing device configured to remove moisture from the drying airflow. 
     
     
         19 . The laundry treatment apparatus according to  claim 17 , wherein the switching device comprises a first switching valve disposed at the air inlet end of the drying air duct and a second switching valve disposed at the air outlet end of the drying air duct, and wherein the first switching valve is configured to selectively communicate the air inlet end of the drying air duct with the first air outlet duct or the second air outlet duct, and the second switching valve is configured to selectively communicate the air outlet end of the drying air duct with the first air inlet duct or the second air inlet duct. 
     
     
         20 . The laundry treatment apparatus according to  claim 14 , wherein the laundry treatment apparatus comprises a plurality of second laundry treatment devices, and the drying system is capable of simultaneously or separately delivering the drying airflow generated by the drying assembly to the interior of the second laundry treatment cylinder of each of the second laundry treatment devices. 
     
     
         21 . The laundry treatment apparatus according to  claim 20 , wherein the engagement device is a multi-position engagement device, and the driving device is further connected to the second laundry treatment cylinder of each of the second laundry treatment devices through the multi-position engagement device so as to selectively drive the second laundry treatment cylinder to rotate. 
     
     
         22 . The laundry treatment apparatus according to  claim 13 , wherein the first laundry treatment device is a dryer or a washing machine. 
     
     
         23 . The laundry treatment apparatus according to  claim 14 , wherein the first laundry treatment device is a dryer, and the second laundry treatment device is a washing machine; or
