In this embodiment, the inner cylinder 1 is made of metal and contains a certain amount of magnetism, the outer cylinder is provided with a magnetic force generating device, the magnetic force applied to the inner cylinder 1 by the outer cylinder can be adjusted by adjusting the magnetic force generating device, and then the folding and unfolding positions of the inner cylinder 1 are adjusted by the magnetic force, so that the inner cylinder 1 can select a proper working volume according to the weight of a washing object, the volume utilization rate of the inner cylinder 1 is improved, the energy utilization rate is improved, and the energy is saved.

Preferably, the outer barrel is provided with a sensor for sensing a change in magnetic force between the outer barrel and the inner barrel 1.

When the washing machine adopting the washing machine barrel is used for washing, a user inputs the washing into the inner barrel 1, the distance between the inner barrel 1 and the outer barrel is changed, so that the magnetic force received by the outer barrel is changed, the sensor can timely transmit the magnetic force received by the outer barrel to the controller, and the controller calculates the weight of the corresponding washing according to the change of the magnetic force of the outer barrel and sends out an instruction for changing the magnetic force of the outer barrel; along with the change of the magnetic force of the outer cylinder, the magnetic force born by the inner cylinder body 1 also changes correspondingly, so that the first curled edge 2 is caused to be folded and unfolded along the force guide rail 7, and the volume of the inner cylinder is changed; when the volume of the inner barrel 1 is unchanged, the guiding device positions and clamps the circumferential relative positions of the first curled edge 2 and the second curled edge 3. Meanwhile, an inner cylinder volume change completion instruction is sent to the controller, after the controller receives the instruction, a washing instruction is sent, and the main motor drives the inner cylinder body 1 with the variable volume to rotate through the transmission shaft 9.

The specific process of the washing machine barrel for adjusting the volume of the inner barrel 1 according to the weight of the washing is as follows: after the washings are put into the inner barrel 1, the distance between the inner barrel 1 and the outer barrel changes under the action of the gravity of the washings, but at the moment, the magnetic flux of the inner barrel and the outer barrel does not change, the acting force between the inner barrel and the outer barrel is only related to the distance between the inner barrel and the outer barrel, the acting force between the inner barrel and the outer barrel is changed due to the change of the distance between the inner barrel and the outer barrel, and the controller calculates and records the weight of the corresponding washings according to the change of the force detected by the sensor on the outer barrel. (when the point magnetic charge on the surface of the magnet is fixed by utilizing the coulomb law and the equivalent magnetic charge method, the acting force F between two magnets is inversely proportional to the square of the magnet spacing R, F=K.times.Q.1.times.Q.2/(R.times.R), and the G.Akoun and J.P.Yonnet papers and the doctor's papers on the past construction are referred to as follows). The controller changes the magnetic quantity on the outer cylinder according to the measured washing weight, the change of the magnetic quantity on the outer cylinder can cause the acting force between the inner cylinder body and the outer cylinder body to change, the inner cylinder body 1 changes along the circumferential direction due to the change of the force of the outer cylinder, and the inner cylinder body 1 stops when the volume of the inner cylinder body 1 does not change, and at the moment, the guide device on the inner cylinder body 1 performs positioning and fixing, so that the volume of the inner cylinder body 1 changes along with the washing weight.

The axial shrinkage of the inner cylinder of the washing machine is mainly realized by a transmission shaft 9, wherein the transmission shaft 9 can adopt an electro-hydraulic push rod with a transmission function which is popular at present or a hydraulic push rod with a transmission function.

After the washing is finished, the transmission shaft 9 is extended to push the inner cylinder body 1 with variable volume out of the washing machine; after the inner cylinder body 1 with variable volume is pushed out of the washing machine, the driving motor releases the pull rope 20, the belt or the hinge; the inner cylinder body 1 with the variable volume can incline along with the release of the pull rope 20, the belt or the hinge by the driving motor until the inner cylinder body is at a set position; after the inner cylinder body 1 with the variable volume is inclined to a designated position, the washings can fall into the washings placing device placed in the earlier stage from the inner cylinder body 1 under the action of self-gravity, so that the washings can be automatically poured. The working effect diagram during autonomous dumping is shown in fig. 2.

After the laundry is automatically dumped, the driving motor retracts to draw the pull rope 20, the belt or the hinge, the inner barrel 1 with the variable volume can be gradually pulled back along with the retraction of the pull rope 20, the belt or the hinge until the axis of the inner barrel 1 with the variable volume is coaxial with the axis of the transmission shaft 9, the driving motor stops rotating and keeps the state at the moment, and an instruction of pulling the inclined inner barrel to retract the inner barrel is sent to the controller. After the controller receives the instruction, a shrinkage instruction of the transmission shaft 9 is sent, the transmission shaft 9 can pull the inner barrel back into the washing machine along the axis until the inner barrel body 1 with the variable volume returns to the designated washing working position, and a waiting instruction of the inner barrel body 1 to the washing working position is sent to the controller, and the next working instruction is sent by the controller.
