The stand may be used to support the housing 20, mount the drum 21, and a main drying system of the laundry treating apparatus, etc. Preferably, the drum 21 is horizontally disposed and used for housing and drying the laundry, i.e., the drum 21 is used for providing a storage space for the laundry. The drum 21 extends in the front-rear direction, and a front end cover 24 is provided at the front end of the drum 21. The front cover 24 is configured to close the front opening of the drum 21, that is, the rear side of the rear wall of the front cover 24 is the inner space of the drum 21. In some embodiments, the drum 21 may also be disposed obliquely with respect to the horizontal plane, or the like.

The primary drying system is configured to cause a drying air flow to enter the drum 21 from one end of the drum 21, preferably, to cause a drying air flow to enter the drum 21 from the rear end of the drum 21. As shown in fig. 2, the annular air outlet structure is coaxial with the drum 21 and disposed at the other end of the drum 21, so that the drying air flow flows out of the drum 21 from the other end of the drum 21 through the annular air outlet structure. Because the drying device is provided with the main drying system and the annular air outlet structure, the airflow field of drying airflow in the roller 21 can be changed, the drying temperature in the roller 21 is reasonably distributed as far as possible, uniform and rapid heating is realized as far as possible, the drying efficiency is improved, and the drying device is high in practicability.

For example, the front cover 24 is provided with an annular structure 241 coaxial with the drum 21, and the annular air outlet structure is provided on the inner peripheral wall or the rear end surface of the annular structure 241. Annular air-out structure includes a plurality of air-out portions, and a plurality of air-out portions are along cylinder 21's circumferential direction equipartition. Further, each air outlet portion includes one air outlet hole 242 or a plurality of air outlet holes 242 arranged in sequence along the front-back direction or a plurality of air outlet holes 242 arranged in sequence along the circumferential direction of the roller 21. In some alternative embodiments, the annular air outlet structure is an air outlet ring coaxial with the drum 21, that is, a plurality of air outlet portions are connected together in sequence. An observation window can be arranged on the front end cover 24, and the annular air outlet structure can be located on the periphery of the observation window.

In some preferred embodiments, the axis of each region of the annular air outlet structure for air outlet is arranged to intersect with the axis of the drum. For example, the axis of the air outlet hole 242 is perpendicular to the axis of the drum 21, so that the airflow field of the drying airflow in the drum can be reasonably arranged.

In some embodiments of the present invention, the laundry treating apparatus further comprises an auxiliary drying system. An auxiliary drying system may be disposed outside the other end of the drum 21, and the auxiliary drying system is configured to suck an air flow from the other end of the drum 21, heat the air flow, and make the heated air flow enter the drum 21 from the other end of the drum 21. For example, the auxiliary drying system is provided at the front side of the drum 21, such as in the front cover 24. In the laundry processing apparatus according to the embodiment of the present invention, the auxiliary drying system is provided, and the air path of the auxiliary drying system is combined with the main drying system, and meanwhile, turbulence is formed in the drum 21, so that the two ends in the drum 21 have the drying temperature close to each other, uniform heating is achieved, the drying efficiency is improved, and the practicability is strong. That is to say, this application compares in current ordinary dryer, can improve the anterior stoving temperature of cylinder 21, consequently is showing and is improving drying efficiency, and can realize the even stoving of the interior clothing of cylinder 21, promotes dryer drying efficiency. Further, the auxiliary drying system preferably causes the airflow to flow out of the drum 21 from one end of the drum to the other end, and after being heated by the auxiliary drying system, the airflow flows into the drum 21 from the other end of the drum to one end of the drum. For example, the auxiliary drying system moves the airflow in the drum 21 forward out of the drum 21, and moves the airflow backward into the drum 21 after being heated by the auxiliary drying system. The auxiliary drying system is positioned on the inner side of the annular air outlet structure.

In some embodiments of the present invention, as shown in fig. 1 and 2, the primary drying system is a heat circulation system configured to allow the drying air flow to flow out from the front end of the drum 21, to be condensed and then heated, and to circulate into the drum 21 from the rear end of the drum 21. Preferably, the heat cycle system may include a hot air hood 41, a condensing part 42, a heating part 43, a main fan 44, and an air duct system. The hot air cover 41 is rotatably disposed at the rear end of the drum 21, and a plurality of ventilation holes are formed in a rear end cover of the drum 21 to supply hot air into the drum 21. The hot air hood 41 is disposed coaxially with the drum 21.

The guide ring 243 may be located within the front end opening of the drum 21. The rear wall of the front cover 24 may be protruded rearward to define an annular guide groove with the annular structure 241, and the drying air may enter the air outlet hole 242 through the annular guide groove.

In some embodiments of the present invention, the auxiliary drying system may include an auxiliary blower 51 and a heating device 52, an air inlet structure and an air outlet structure are disposed on a rear wall of the front end cover 24, and the auxiliary blower 51 is configured to promote air in the drum 21 to enter the front end cover 24 through the air inlet structure, and to enter the drum 21 again from the air outlet structure after exchanging heat with the heating device 52. The hot air flow blown out from the air outlet structure by the auxiliary fan 51 and the drying air flow blown out from the rear part by the main fan 44 act together to form turbulent flow at the front part of the roller 21, so that the temperature of clothes at the front part of the roller 21 is improved, and uniform drying temperature is formed at the front and the rear parts of the roller 21, thereby improving the drying efficiency. An auxiliary heating device 52 is provided to accelerate the evaporation of moisture from the laundry.

Because a heater and a fan are generally disposed at the rear of the laundry treating apparatus in the conventional laundry treating apparatus, hot air flows from the rear to the front in the drum 21, so that the temperature at the rear of the drum 21 is significantly higher than that at the front, and the temperature difference is large, and therefore, laundry at the front of the drum 21 is dried slowly, and the drying efficiency is low. According to the invention, the auxiliary drying device is arranged on the front end cover 24, so that the drying temperature of the front part of the roller 21 can be increased, and the drying efficiency is obviously improved.
