Washing machine's urceolus is usually formed by two barrel axial butt joints, and among the correlation technique, two barrels are connected through a plurality of screws along circumference, because there is great interval between two adjacent screws, can lead to sealed effect poor, need use rubber seal to seal between two barrels, and the condition of leaking has taken place easily for a long time, and the assembling process is loaded down with trivial details, extravagant manual work.

In view of this, as shown in fig. 1 to 3, the present disclosure provides an outer tub of a laundry treating apparatus, which may include a first tub 1 and a second tub 2 axially butted to form a space for accommodating the inner tub, wherein a connection end of one of the first tub 1 and the second tub 2 is formed with an internal thread, and a connection end of the other is formed with an external thread to be matched with the internal thread, and the internal thread and the external thread may be integrally formed on the tub, respectively, which can reduce the use of connection parts, and only two tubs need to be screwed up by rotating the threads at the time of assembly, which is convenient in operation and saves the assembly process. Here, the outer tub and the inner tub located in the accommodating space constitute a washing zone for washing or drying. In an embodiment of the present disclosure, the laundry treatment apparatus mentioned above may be a washing machine, and may also be a laundry dryer, and is not particularly limited herein.

Through the technical scheme, the first barrel body 1 and the second barrel body 2 are tightly connected through the threads, so that the assembly process of the outer barrel can be simplified, when the outer barrel is assembled, the first barrel body 1 and the second barrel body 2 only need to be closed along the axial direction and screwed down in a rotating manner, the assembly process is simple, and time and labor are saved; and can reduce spare part, simple structure, for example, reduce fastener and the sealing washer between first barrel 1 and the second barrel 2 among the correlation technique, consequently, be favorable to guaranteeing the stability of first barrel 1 and the assembly of second barrel 2, and two barrels can not take place the skew in the connection process, strengthen sealed effect, avoid taking place to leak, cause to damage clothing treatment facility to clothing treatment facility's life has been promoted.

According to an exemplary embodiment of the present disclosure, referring to fig. 2, the connection end of the first cylinder 1 is provided with an annular first boss 11 protruding in the axial direction, specifically, the outer diameter of the first boss 11 is smaller than the inner diameter of the second cylinder 2, the outer circumference of the first boss 11 may be formed with an external thread, the inner wall of the connection end of the second cylinder 2 may be formed with an internal thread matched with the external thread on the first boss 11, the first boss 11 and the second cylinder 2 are tightly matched through threaded connection, and the outer circumferential surfaces of the side walls of the first cylinder 1 and the second cylinder 2 are flush, thereby achieving the effect of tidy appearance and also increasing the reliability of sealing.

Further, the inner wall of the second cylinder 2 may be provided with an annular sealing rib, specifically, the sealing rib may extend in the axial direction and may be integrally formed on the inner wall of the second cylinder 2, when the threads of the first cylinder 1 and the second cylinder 2 are screwed, the sealing rib abuts against the inner wall of the first boss 11, water in the cylinders does not enter the threaded area, and the sealing rib is integrally formed on the cylinders, so that the situation of position deviation and even falling off does not occur, and the sealing performance is good. Here, the material of the sealing rib may be the same as that of the cylinder, and polypropylene may be selected.

According to another exemplary embodiment of the present disclosure, referring to fig. 3, the connecting end of the first cylinder 1 is provided with a second boss 12 in a ring shape protruding radially, specifically, the inner diameter of the second boss 12 is larger than the outer diameter of the second cylinder 2, an inner thread may be formed on the inner wall of the second boss 12, an outer thread matching with the inner thread on the second boss 12 may be formed on the connecting end of the second cylinder 2, and the second boss 12 and the second cylinder 2 are tightly matched through threaded connection.

Further, the connecting end of the second cylinder 2 may be provided with an annular sealing rib protruding axially, and after the first cylinder 1 and the second cylinder 2 are screwed, the sealing rib abuts against the inner wall of the first cylinder 1, so that water in the cylinders does not enter the threaded connection area, the sealing effect is enhanced, and leakage is avoided.

Specifically, the number of turns of the internal thread and the external thread can be more than two turns, for example, the number of turns of the internal thread and the external thread can be three turns, four turns and the like, and the number of turns of the internal thread and the external thread can be specifically adjusted according to actual requirements, so that reliable connection between the internal thread and the external thread can be realized.

In order to prevent the connection between the first cylinder 1 and the second cylinder 2 from being loosened when the laundry treating apparatus is operated to be shaken. In an embodiment of the present disclosure, referring to fig. 1, the outer tub of the laundry treating apparatus may further include a locking device 3 disposed between the first and second tubs 1 and 2 for limiting rotation of the first and second tubs 1 and 2 when the first and second tubs 1 and 2 are tightly coupled, i.e., locking the first and second tubs 1 and 2 in a tightly coupled state, to avoid loosening of the screw coupling due to rotation.

The anti-loosening device 3 may be constructed in any suitable structure. In the embodiment of the present disclosure, referring to fig. 1, the anti-loose device 3 may include an anti-loose hook 31 provided on the first cylinder 1 and a pressing block 32 provided on the second cylinder 2, the anti-loose hook 31 having an inclined surface for the pressing block 32 to slide over and an upright surface for abutting against the pressing block 32, specifically, a screw is screwed when the outer cylinder is installed, at a limit position, the pressing block 32 is stroked along the inclined surface of the anti-loose hook 31 so that the pressing block 32 moves from one side of the inclined surface of the anti-loose hook 31 to one side of the upright surface, the pressing block 32 abuts against the upright surface of the anti-loose hook 31, at which time, the anti-loose device 3 is in a locked state, and the pressing block 32 is engaged with the anti-loose hook 31; when the anti-loosening device 3 needs to be disassembled, the anti-loosening hook 31 or the pressing block 32 is pressed to enable the pressing block 32 to be withdrawn from one side of the vertical surface of the anti-loosening hook 31 to one side of the inclined surface, and at the moment, the anti-loosening device is in an unlocking state. Further, in the embodiment of the present disclosure, the height of the anti-back hook 31 is higher than or equal to the height of the pressing block 32, so as to avoid the pressing block 32 from coming off from the vertical surface of the anti-back hook 31 in the locked state, and improve the tightness of the anti-loose device 3.

Further, the anti-back-off hook 31 or the pressing block 32 may be made of an elastic material, or both the anti-back-off hook 31 and the pressing block 32 are made of an elastic material. In the embodiment of the present disclosure, the anti-receding hook 31 is made of an elastic material, when the locking and unlocking are performed, only the anti-receding hook 31 needs to be pressed to cause elastic deformation, so that the pressing block 32 can slide on the anti-receding hook 31, after the pressure disappears, the anti-receding hook 31 immediately recovers the elastic deformation to be able to clamp the pressing block 32, and the first cylinder 1 and the second cylinder 2 are prevented from rotating when the locking is performed, so that the threaded connection is not loosened.
