Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples.

Referring to fig. 1-4, the full-automatic washing machine without a clutch mechanism comprises an outer barrel 1 and an inner barrel 2, wherein the bottom of the inner barrel 2 is provided with a wave wheel 3, the wave wheel 3 is connected with a power main shaft 4 in a matching way, the full-automatic washing machine further comprises a support 5, a main shaft sleeve 6 and a main shaft bearing 7, the support 5 is arranged in the outer barrel 1, the support 5 is connected to the bottom of the inner barrel 2, the support 5 is sleeved on the main shaft sleeve 6, the support 5 and the main shaft sleeve 6 are connected into a whole, and the main shaft sleeve 6 is sleeved on the power main shaft 4 through the main shaft bearing 7.

The main shaft bearing 7 is a sliding bearing.

The main shaft bearing 7 is of a single bearing structure, the supporting width of the single bearing is a, and a is more than or equal to 15mm; or the main shaft bearing 7 is of a multi-bearing structure, the supporting width of the multi-bearing is b, and b is more than or equal to 15mm; the above structure can ensure the inner barrel 2 to rotate freely but not to shake obviously.

The center of the support 5 is provided with a mounting hole 5.1, the main shaft sleeve 6 is provided with a flange-shaped mounting part 6.1, and the mounting part 6.1 is matched with the mounting hole 5.1 for mounting, so that the support 5 is connected with the main shaft sleeve 6, and the transmission of the main shaft sleeve 6 and the support 5 is more stable.

The impeller 3 is embedded with a first absorbing part 8, the bottom of the inner barrel 2 is embedded with a second absorbing part 9, the first absorbing part 8 is uniformly distributed on the impeller 3 along the circumference, the second absorbing part 9 is uniformly distributed at the bottom of the inner barrel 2 along the circumference, and the first absorbing part 8 and the second absorbing part 9 are arranged at corresponding positions up and down.

The inner barrel 2 comprises a barrel body 2.1 and a bottom shell 2.2 connected to the bottom of the barrel body 2.1, the bottom shell 2.2 is connected with a bracket 5 in a matching way, and the impeller 3 is arranged in the bottom shell 2.2.

The first absorbing part 8 and the second absorbing part 9 are both magnets, or the first absorbing part 8 and the second absorbing part 9 are a combination of magnets and iron sheets; the second suction element 9 is embedded inside the bottom shell 2.2; the uniform distribution quantity of the first absorbing component 8 and the second absorbing component 9 can be more or less, and the dehydration synchronous rotation effect is determined; since the magnetic force is large when the magnet is close to the magnet (or the iron piece), and is rapidly reduced with the increase of the distance, such characteristics of the magnet are utilized in washing and dehydration.

When washing or rinsing, the impeller 3 is driven by the power main shaft 4 to rotate rapidly, and the inner barrel 2 is in a free state and can only follow the rotation at a low speed due to friction; the first absorbing part 8 on the impeller 3 is close to the second absorbing part 9 on the bottom shell 2.2 only in instantaneous distance, so that stable and powerful magnetic traction cannot be formed, and the bottom shell 2.2 cannot be effectively driven to rotate when the impeller 3 rotates at high speed. Thus, the impeller 3 rotates at a high speed, and the bottom shell 2.2 rotates at a low speed, so that the clothes are washed by differential scrubbing water flow.

During dehydration: the impeller 3 is driven by the power main shaft 4 to rotate slowly firstly, so that a first absorbing piece 8 on the impeller 3 and a second absorbing piece 9 on the bottom shell 2.2 are sufficiently short-distance acted for time, and stable and powerful magnetic traction is formed; thus, the impeller 3 slowly pulls the bottom shell 2.2 to rotate at a low speed and gradually speeds up to the normal dehydration rotating speed to realize dehydration.

The power main shaft 4 sequentially penetrates through the bottom of the outer barrel 1 and a main shaft bearing 7 and then is connected with the impeller 3; the impeller 3 is fixed at the top end of the power main shaft 4 through a screw.

The bottom of the outer barrel 1 is provided with a driver 10, and the driver 10 is connected with the power spindle 4 in a driving manner.

The driver 10 is a motor assembly including a washing motor or a washing motor with a deceleration structure.

The working principle of the washing machine is as follows:

washing/rinsing state: water is fed into the outer barrel 1 of the washing machine, and the motor transmits torque through the power main shaft 4 to drive the impeller 3 to rotate forward and backward, so that clothes are washed; because the inner barrel 2 is sleeved on the power main shaft 4 through the bracket 5, the main shaft sleeve 6 and the main shaft bearing 7, the inner barrel is in a free rotation state and cannot instantly rotate along the same direction of the impeller 3; in the process, the inner barrel 2 is delayed and rotates along with the friction action of the power main shaft 4, the main shaft bearing 7 and the main shaft sleeve 6, and the water flow stirred by the impeller 3 also drives the inner barrel 2 to delay and rotate along with the rotation; because the wave wheel 3 continuously rotates forward and backward and the inner barrel 2 continuously delays to rotate, the wave wheel 3 and the inner barrel 2 frequently rotate in opposite directions in the rotation process, so that the clothes overturning and scrubbing effects are better.

And (3) dehydration state: after the washing machine finishes draining, preparing to enter a dehydration state, and driving the power spindle 4 to rotate by the washing motor at the moment; because the main shaft sleeve 6 is connected with the bracket 5 and the inner barrel 2 into a whole, the inner barrel 2 starts to synchronously rotate under the driving of the friction force of the power main shaft 4, the main shaft bearing 7 and the main shaft sleeve 6; along with the gradual acceleration of the rotating speed, the inner barrel 2 and the impeller 3 rotate synchronously and rapidly step by step to realize dehydration.

The foregoing is a preferred embodiment of the present invention showing and describing the basic principles, main features and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are intended to illustrate the principles of the invention, and that various changes and modifications may be made without departing from the spirit and scope of the invention, and the scope of the invention is to be protected. The scope of the invention is defined by the appended claims and equivalents thereof.
