Detailed Description

The device comprises an outer cylinder and a washing cylinder 2, wherein the outer cylinder is divided into an outer cylinder rear part 1 and an outer cylinder front part 7, and the outer cylinder rear part 1 and the outer cylinder front part 7 are fixedly installed together through screws. The washing cylinder 2 passes through a bottom mounting hole of the rear part 1 of the outer cylinder through a washing cylinder flange 3 and a shaft 4 which are fixed mutually, the washing cylinder flange 3 and the shaft 4 are movably and concentrically mounted together through a bearing 5 and a large water seal 6, and the shaft 4 passes through the outer part of the rear part 1 of the outer cylinder and is fixedly provided with a belt pulley or a motor rotor to provide power for the washing cylinder.

A door hinge 10 is fixed on the front part 7 of the outer cylinder. The movable door is composed of an inner door 13 and an outer door 12, which are movably mounted together by a door bearing 15, and the inner door 13 rotates around the axis of the outer door 12.

The outer door 12 is also provided with a door handle 18 and a buckle 17 fixed on the door handle 18, the door handle and the buckle are movably arranged on the outer door 12 through a handle pin shaft 19 and can rotate for a certain angle around the handle pin shaft 19, and a reset torsion spring is also arranged on the handle pin shaft 19. And the other end of the outer door 12 opposite the door handle 18 is movably mounted on the door hinge 10 by a door pin 11. The door hinge 10 is fixed to the outer tub front 7. Thus, the inner door 13 and the outer door 12 can be rotated through a certain angle with respect to the outer tub, and in a closed or open state.

A rubber ring 16 is also fixedly mounted on the inner door 13.

The front part 7 of the outer cylinder is provided with a clamping groove 8.

The washing barrel mouth part 9 at the end part of the washing barrel 2 is arranged in a circular ring structure which is concentric relative to the axial lead of the washing barrel 2 and has a smooth inner surface and/or outer surface or/and a smooth plane, and the rubber ring 16 can be matched with at least one surface of the washing barrel mouth part 9 to achieve the sealing effect.

The cross section of the buckle 17 is composed of a guide inclined plane and a stopping straight plane, the bayonet groove 8 is arranged on the front part 7 of the outer cylinder, in the closing process of the movable door, the guide inclined plane of the buckle 17 acts on the edge of the buckle groove 8, when the movable door is under the action of external force, the force of pushing the movable door makes the buckle have downward pressure, and the downward pressure of the buckle 17 is converted into lateral pushing force under the action of the guide inclined plane, so that the buckle 17 rotates. When buckle 17 rotates certain angle, buckle 17's direction inclined plane is drawn the edge of buckle groove 8, and buckle 17 reverses certain angle under the effect of reset torsion spring for buckle 17's straight face acts on the edge of buckle groove 8 and the stopping, and this is the lock state. When the movable door is opened, the door handle 18 and the buckle 17 on the door handle are pulled to overcome the torsion of the reset torsion spring, the door handle 18 can rotate a certain angle around the handle pin shaft 19, so that the stopping straight surface of the buckle 17 is separated from the buckle groove 8, the whole movable door rotates around the door pin shaft 11 again, and then the movable door is opened, so that the clothes can be conveniently taken and put.

The outer door 12 is provided with an elastic body around the outer door, and when the movable door is in a closed state, the elastic body enables the outer door 12 and the outer cylinder front part 7 to have a sealing effect, and the elastic body can be rubber or other materials with the sealing effect. When the movable door is closed, the water in the washing drum can not flow out from the space between the front part 7 of the outer drum and the movable door.

The middle part of the outer door 12 is provided with a door center hole 14, a water inlet pipeline is fixedly arranged on the outer door 12, the water inlet pipeline is externally connected with a water inlet valve or a washing powder box, the outlet of the water inlet pipeline is arranged at the door center hole 14 at the middle part of the outer door 12, and water flows into the washing barrel 2 from the door center hole.

In the device, when water is fed and washed, the movable door is closed, water fed by the water inlet valve flows into the washing drum 2 from the door central hole 14 in the middle of the outer door 12 through the water inlet pipeline, when the water level reaches a certain amount, the washing drum 2 rotates, the inner door 13 and the rubber ring 16 on the inner door rotate along with the washing drum 2, and the outer door does not move. Since the amount of water is lower than the center line when the drum washing machine washes, the water in the washing drum can not flow out from any place. During dewatering, the water in the washing drum flows out from a water switch at other places, which is not explained here, and the inner door 13 and the rubber ring 16 thereon rotate together with the washing drum 2.

Fig. 5 and fig. 6 are schematic diagrams of a movable door cover with an electromagnetic clutch device according to a second embodiment of the present invention, where fig. 5 is a closed state diagram of the movable door with an electromagnetic clutch, fig. 6 is an open state diagram of the movable door with an electromagnetic clutch, an inner spline structure is disposed in the middle of the inner door 13, a clutch sleeve 20 with an outer spline is sleeved outside the door bearing 15, and the inner door 13 and the outer door 12 can rotate circumferentially and move axially for a certain distance. An electromagnetic coil 22 is fixed on the outer door 12, and a corresponding magnetic conduction ring and a reset pressure spring 21 are arranged on the inner door 13. When the electromagnetic coil 22 is de-energized, the pressure spring 21 is reset, the inner door 13 and the rubber ring 16 fixedly arranged on the inner door are pushed to move towards the washing cylinder 2, so that the rubber ring 16 is pressed on the opening 9 of the washing cylinder to achieve the sealing effect, and the water inlet and washing processes are carried out at this time. When the electromagnetic coil 22 is electrified, the magnetic conduction ring on the inner door 13 is stressed, so that the inner door 13 and the rubber ring 16 fixedly arranged on the inner door overcome the elasticity of the reset pressure spring 21 and move towards the opposite direction of the washing cylinder 2, and the rubber ring 16 is separated from the opening 9 of the washing cylinder, which is a drainage and dehydration process, and the inner door 13 and the rubber ring 16 on the inner door are not in contact with the washing cylinder 2 at this time.

Fig. 7 to 9 are schematic diagrams of a movable door cover of a buffer sealing ring according to a third embodiment of the present invention, where fig. 7 is a closed state diagram of the movable door of the buffer sealing ring, fig. 8 is an opened state diagram of the movable door of the buffer sealing ring, and fig. 9 is a schematic diagram of a structure of the buffer sealing ring; the movable door is an integral combined door 23, the combined door 23 is movably arranged on the outer door 12 through a door bearing, a buffering sealing ring 24 is fixedly arranged on the excircle of the combined door 23, the buffering sealing ring 24 is provided with an inner ring and an outer ring which are formed by a buffering sealing ring framework part 241 of an inner supporting structure and a buffering sealing ring lip part 24 of an outer rolling sealing part, and a buffering sealing ring elastic part 242 is arranged between the inner ring and the outer ring and has stronger elasticity. When the movable door is closed, the lip part 243 of the buffer sealing ring 24 and the washing tube opening 9 are movably sealed, the two can freely rotate, the combination door 23 and the buffer sealing ring 24 on the combination door do not rotate when the washing tube 2 rotates, but because the buffer sealing ring 24 has strong elasticity, the bounce generated when the washing tube rotates can not damage the sealing effect. Closing and opening as in the previous embodiment 1, without further recitation.
