As shown in fig. 3, when the second pin sleeve 32 is an independent component, the second pin sleeve 32 is embedded in the groove of the door 10 and is sleeved on the pin 33 at a position staggered from the first pin sleeve 311.

According to the embodiment of the present application, the door assembly 100 further includes a combination lock disposed on the door body 10 on a side opposite to the door hinge 30, the combination lock includes a long bolt 51 and a short bolt (not shown in the figure) disposed on the door body 10, and in a case that the driving device 40 pushes the door body 10 in the door opening direction, the short bolt is separated from the front sealing door, and the long bolt 51 extends into the front sealing door 20 and slides in the door opening direction relative to the front sealing door 20.

In this embodiment, the door lock 50 includes a long bolt and a short bolt (not shown in the figure) disposed on the door body 10, in the case that the door body 10 is translated along the door opening direction, the short bolt is separated from the front sealed door, the long bolt 51 extends into the front sealed door 20 and slides along the door opening direction relative to the front sealed door 20, the front sealed door 20 is disposed with a PTC lock 21 engaged with the long bolt 51, and an automatic ejection lock 22 engaged with the short bolt, when the door body 10 is in the closed state, the long bolt 51 is inserted into the PTC lock 21 along the door opening direction, the short bolt is inserted into the automatic ejection lock 22 along the door opening direction, the PTC lock 21 applies a locking force along the door closing direction to the long bolt 51, the automatic ejection lock 22 applies a locking force along the door closing direction to the short bolt, and when a pushing force along the door opening direction is applied to the door body 10, the short bolt can be easily separated from the automatic ejection lock 22 under the driving of the door body 10, the long bolt 51 is hung in the PTC lock 22 and slides in the door opening direction relative to the front sealing door 20, so that the door 10 can realize the integral translation effect under the action of the pushing force. Meanwhile, the long latch tongue 51 is hung in the PTC lock body 21 and slides towards the door opening direction relative to the front sealing door 20, so that not only can the door 10 be supported and guided, but also the phenomenon that clothes fall off after the door 10 is completely opened can be reduced, that is, the door 10 is wholly translated under the thrust of the driving device 40, only a circle of air holes are formed at the periphery of the door, the purpose of completely opening the door 10 is not achieved, and when clothes are required to be taken, the door 10 also needs to be manually opened.

In particular, after the laundry treating apparatus completes its operation, taking the laundry treating apparatus as a dryer as an example, after the dryer finishes the drying program, the controller of the dryer records the finishing time of the drying program, and obtains the opening and closing information of the door body 10 detected by the angle detection unit, when the door 10 is still not opened within a preset time (e.g. 1min) after the dryer executes the drying procedure, at this time, the controller sends an automatic door opening instruction to the control unit of the driving device 40, the control unit controls the motor of the driving device 40 to be communicated with the power supply, the driving device 40 drives the door body 10 to translate along the door opening direction, the door body 10 drives the lock tongue 51 on the door body 10 to be separated from the lock body on the front sealing door 20 in the process of translating along the door opening direction, therefore, a circle of ventilation gap is formed between the door body 10 and the front sealing door 20, and the dryer conducts ventilation and heat dissipation through the circle of ventilation gap between the door body 10 and the front sealing door 20.

It should be noted that the clothes treating apparatus may be one of a washing machine, a clothes dryer or a dry cleaning all-in-one machine, and the clothes treating apparatus has all the technical effects of the door hinge 30 of the clothes treating apparatus of the first aspect of the present invention, and will not be described herein again.

In addition, the above-described embodiments have been described in detail only with respect to the structure of the laundry treating apparatus related to the innovative points of the present invention, and the structure of the laundry treating apparatus not related to the innovative points of the present invention will not be described in detail herein.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
