Referring to fig. 6 and 1, in some embodiments of the present invention, the push plate 4 is relatively fixedly installed on the tub 2, the rail groove 31 extends in the up-down direction, and the push plate 4 has a pushing portion 41, the pushing portion 41 being located below the slide shaft 32 and adapted to push the slide shaft 32 upward. Thereby, the sliding shaft 32 can be pushed to move upwards by the push plate 4, so that the synchronous rotation of the tub 2 and the door 3 can be realized.

The push plate 4 is in the second state when the slide shaft 32 is positioned at the lower end of the rail groove 31. The push plate 4 is spaced apart from at least one of the door 3 and the tub 2 in the second state of the push plate 4. This may reduce vibration of the washing machine 100 during laundry washing.

Further, when the tub 2 is at the lower limit position, an angle between a line L1 of the rotation center shaft and the pushing part 41 and a line L2 of the rotation center shaft and the lower end of the rail groove 31 is in a range of 0 ° to 5 °. In other words, when the tub 2 is at the lower limit position, the projection of the rotation center axis on the plane passing through the axis of the tub 2 and perpendicular to the rotation center axis is a point whose angle between the line L1 of the pushing part 41 and the line L2 of the point with the lower end of the rail groove 31 is in the range of 0 ° to 5 °. Here, the pushing part 41 is located at the same side of the tub 2 as the corresponding rail groove 31.

That is, when the tub 2 is at the lower limit position, the push plate 4 is separated from the slide shaft 32, i.e., the push plate 4 is not in contact with the slide shaft 32, and at this time, the push plate 4 is positioned under the slide shaft 32, and when the tub 2 is rotated by 0 ° to 5 °, the push plate 4 is in contact with the slide shaft 32, the slide shaft 32 can be pushed to slide upward along the rail groove 31 by the push plate 4, thereby synchronously rotating the tub 2 and the door 3.

The washing machine 100 further includes an electric push rod 5, and the rotation of the tub 2 about the rotation center axis may be pushed by the electric push rod 5.

Referring to fig. 6, according to some embodiments of the present invention, push plates 4 are provided at both left and right sides of the tub 2. Therefore, the corresponding sliding shafts 32 on the door body 3 can be respectively pushed by the push plates 4 on the left side and the right side, so that the sliding shafts 32 can slide along the track grooves 31, and the synchronous rotation of the barrel body 2 and the door body 3 is realized.

One or more pushing plates 4 are disposed on the left and right sides of the barrel body 2, for example, the number of pushing plates 4 disposed on one side (for example, the left side or the right side of the pushing plate 4) of the barrel body 2 may be one, two, three, etc., so that the door body 3 can be pushed to rotate by the pushing plates 4 better.

A specific embodiment of the washing machine 100 according to the present invention is described in detail below with reference to the accompanying drawings.

The door body 3 rotates on the track grooves 31 fixed on the left side and the right side of the washing machine box body (for example, the supporting frame 1) through four sliding shafts 32 and four rolling bearings 321; the door body 3 is pushed by pushing plates 4 fixed on the left and right sides of the tub body 2. When the electric push rod 5 pushes the barrel body 2 to rotate, the barrel body 2 and the door body 3 rotate together to wash under the action of the push plates 4 on the left side and the right side.

The door body 3 is fixed to the door body supports 11 on the left and right sides by four slide shafts 32 and four rolling bearings 321. The door body 3 can rotate up and down along the arc track groove 31 on the door body support 11.

Two pushing plates 4 are respectively fixed on the left side and the right side of the barrel body 2, when the electric push rod 5 is electrified, the barrel body 2 starts to rotate, and after the barrel body 2 rotates for 3 degrees, the pushing plates 4 on the left side and the right side can support the door body 3 to move upwards along the track groove 31 in a rotating mode. When the tub 2 rotates downward, the door 3 rotates downward along the rail groove 31 under the self weight of the door 3. When the lowest point of the track groove 31 is reached, the door body 3 stops rotating, and the barrel body 2 continues to rotate downwards for 3 degrees and then stops. Separation of the tub 2 and the door 3 (referred to as separation of the push plate 4 from the slide shaft 32) is achieved.

Four slide shafts 32 are fixed to the door body 3, four rolling bearings 321 are assembled in the rail grooves 31, the rail cover 111 is pressed against the rolling bearings 321, and the rail grooves 31 and the rolling bearings 321 are fastened to the slide shafts 32 by screws and the rail plates 112. The push plates 4 at the left side and the right side are fixed on the barrel body 2 by using screws, the electric push rod 5 is fixed on the supporting frame 1 by using screws, and one movable end of the electric push rod 5 is fixed on the barrel body 2.

The operation of the washing machine 100 according to the embodiment of the present invention is described in detail with reference to fig. 1 to 6.

Specifically, in order to achieve 720 ° washing, the tub 2 and the door 3 are required to rotate together about the rotation center axis. At this time, the electric push rod 5 is electrified to push the barrel body 2 to rotate. When the tub 2 rotates by 3 °, the push plates 4 on the left and right sides can support the door 3 to move upward along the rail groove 31 together. When the tub 2 rotates downward, the door 3 rotates downward along the rail groove 31 under the self weight of the door 3. When the lowest point of the track groove 31 is reached, the door body 3 stops rotating, and the barrel body 2 continues to rotate downwards for 3 degrees and then stops. The separation of the barrel body 2 and the door body 3 is realized. The vibration of the barrel body 2 is prevented from being transmitted to the door body 3, and the shaking and vibration of the door body 3 are reduced.

720 ° washing means that the laundry in the tub 2 can perform 720 ° washing, specifically, when the tub 2 rotates 360 ° around the axis of the tub 2, the laundry in the tub 2 can perform 360 ° washing along with the tub 2, and when the tub 2 rotates a predetermined angle (e.g., 45 °) around the rotation center axis, the laundry in the tub 2 can finish 360 ° turning along with the tub 2, thereby achieving 720 ° washing of the laundry. The predetermined angle of rotation of the tub 2 about the rotation center axis may be adaptively set according to actual needs.

The door body 3 is fixed to the rail groove 31 via the slide shaft 32 and the slide bearing 321, and moves along a specific trajectory; the initial position of the barrel body 2 is separated from the door body 3, when the barrel body 2 rotates for 3 degrees, the push plates 4 on two sides of the barrel body 2 can contact the door body 3 and push the door body 3 to rotate together, so that the vibration of the barrel body 2 is prevented from being transmitted to the door body 3, and the shaking and vibration of the door body 3 are reduced. The rotation center axis of the tub 2 and the rotation center axis of the door 3 are collinear, and the tub 2 and the door 3 rotate around the rotation center axis together for washing. The operation of the washing machine 100 according to the embodiment of the present invention is thus completed.
