Specifically, a torsion spring (not shown) is further fitted around the door shaft 22, and one end of the torsion spring abuts against the drum door 21; after the hook 15 is separated from the hanging hole on the locking protrusion 14, the roller door 21 can be automatically ejected from the roller 1 under the action of the torsion spring, that is, the roller door 21 is opened. When the roller door 21 is opened, the electromagnet 8 is powered off, the push block 9 is restored to the initial position, and meanwhile, the lock cylinder rod 13 is also reset until the roller door 21 is opened next time, and the unlocking mechanism works repeatedly.

Specifically, as shown in fig. 3, a containing cavity is provided in the laundry beating device 10, a limiting protrusion is provided on the lock cylinder bar 13, and the return spring 12 is disposed in the containing cavity and between the limiting protrusion and the inner wall of the containing cavity.

Specifically, as shown in fig. 1, a pinch roller assembly 7 is further installed on the inner wall of the housing 3, the pinch roller assembly 7 includes a roller and a roller driving unit, and the roller is abutted to the outer wall of the roller 1 or not abutted to the outer wall of the roller 1 through the roller driving unit. Here, the roller driving unit may be a motor 19, a hydraulic cylinder or an air cylinder, and is in transmission connection with the roller through a rack and pinion structure, a screw rod structure or a connecting rod, etc., so as to adjust the relative distance between the roller and the outer wall of the drum 1.

Pinch roller subassembly 7's effect lies in automatic locking roller door 21, specifically is: the opening direction of the drum door 21 is set to be the same as the rotation direction of the drum 1, for example, if the drum 1 is set to rotate clockwise, the drum door 21 is set to rotate clockwise to open. When the washing machine roller 1 starts to work, the roller 1 rotates, the roller of the pressure wheel assembly 7 is abutted against the roller door 21, the roller door 21 is pressed by the external roller, the locking protrusion 14 of the roller door is pressed into the locking opening of the washing and beating device 10, and the hook 15 on the lock core rod 13 is buckled into the hanging hole on the locking protrusion 14, so that the roller door 21 is locked. In order to reduce unnecessary friction between the roller and the drum door 21, the pinch roller assembly 7 is operated only when the washing machine is just started and is rotated at a low speed, and after the pinch roller assembly 7 is rotated at a high speed, the roller is retracted by the roller driving unit of the pinch roller assembly 7 to keep a certain distance from the drum door 21.

In practical application, an operator can select to close the roller door 21 manually, or can close the roller door 21 automatically by the pressing wheel assembly 7.

Specifically, as shown in fig. 4-5, two sides of the drum 1 are respectively connected with the housing 3 through a drum power shaft 20 and a drum driven shaft 18, the end of the drum power shaft 20 is connected with a motor 19, a first bearing 16 and a first sealing ring 33 are arranged between the drum driven shaft 18 and the housing 3, and a second bearing 17 and a second sealing ring 34 are arranged between the drum power shaft 20 and the housing 3; here, the first seal ring 33 and the second seal ring 34 are used for waterproofing.

Specifically, as shown in fig. 1-2, the laundry machine further comprises an upper cover 6, wherein an opening of the upper cover 6 is larger than an opening of one of the drum doors 21 of the drum 1 when the drum door is opened, so that the laundry is conveniently taken out.

Specifically, the shell 3 is also provided with a water inlet interface 5, a detergent box 4 and a washing water tank 2; since the position relationship and the connection relationship of the above components are already known in the prior art, they are not described herein in detail.

The working principle of the technical scheme is as follows: when all the drum doors 21 are locked by the cylinder bar 13, a cylindrical drum 1 is constructed. When the washing of the clothes is finished, the drum 1 stops rotating and stays at a certain position; open washing machine upper cover 6, the sensing of top door switch sensor 11 is to the 6 door opening signals of upper cover, and release mechanism starts, and 8 drive ejector pad 9 butts of electro-magnet are located the locking core pole 13 of cylinder 1 top to promote locking core pole 13 to remove, make couple 15 and the hanging hole separation on the lock protruding 14, the cylinder door 21 of the top is automatic to pop out from cylinder 1 under the effect of torsional spring, rotates along door-hinge 22, and cylinder door 21 opens promptly, takes out the clothing. If the clothes need to be cleaned again, after the clothes are put in, the upper cover 6 is closed, a washing program is started, the roller door 21 at the top is automatically locked under the action of the pressure roller assembly 7, and when the clothes are operated at a high speed, the roller driving unit of the pressure roller assembly 7 retracts the roller, so that a certain distance is kept between the roller and the roller door 21; or after the clothes are put in, the hanging hole of the locking protrusion 14 of the drum door 21 is manually buckled with the hanging structure, and then the upper cover 6 is closed to start the washing program.

The part that does not relate to in the device all is the same with prior art or can adopt prior art to realize, the utility model has the advantages of being scientific and reasonable in structure, convenience safe in utilization provides very big help for people.
