One end of the fork rocker arm 24 is connected with the valve stem of the drain valve, and the other end extends into the shaft wall hole 25 of the hollow rotating shaft of the flange.

The four jiaos of casing top are fixed with support 12, and the support 39 that is positioned at washing tub below is connected with support through suspender 13. There is a damping tube 19 at the lower end of the boom; an angular contact ball bearing 27 supporting the hollow rotating shaft of the flange is arranged above the support middle beam 44, and a motor 36 and a sensor head 28 are arranged below the middle beam, and the hollow rotating shaft of the flange passes through the pulley group 35 and The belt is connected to the motor 36, and the lower part of the hollow shaft of the flange is covered with a shaft limit ring 31, a radial ball bearing 30 and a magnetic rotor 29. The sensor head monitors the rotation speed of the washing tub through the magnetic field change of the magnetic rotor and transmits the monitoring data. to the program control agency. A ball 37 is arranged between the hollow rotating shaft of the flange and the joystick, and an electromagnet 32 is arranged under the hollow rotating shaft of the flange. Two sumps 26 are arranged at the lower part of the support, which are located on both sides of the center beam. The bottom of the sump has an outer drain hole 33, and a rubber funnel 40 glued to the bracket is arranged above the center beam. The rubber funnel and the groove of the sump There is a corresponding mouth at the corresponding place of the mouth, and the ribs on its periphery are hung in the water retaining plate groove 22 on the casing by the buckle hook 23.

If a sprinkler is installed at the lower backflow hole, the upper backflow hole can be sealed to increase the spray pressure; when high-grade clothes need to be washed, in order to avoid mesh cracking and deformation of the clothes, the backflow hole in the washing tub can be used The orifice is plugged to prevent circulation of the wash solution.

When a large amount of clothing needs to be washed, the neck ring 45 can be installed on the mouth of the washing tub. The necking ring is a ratchet-type hollow structure, as shown in Figure 2 and Figure 3, the necking ring includes a pawl shell ring 48, a ratchet ring 49, a pawl 50 on the pawl shell ring, and the ratchet ring is set on the pawl The shell ring is connected with the positioning pin 46, so that the ratchet ring and the pawl shell ring are in clearance fit.

When in use, press the neck ring into the neck of the washing bucket, and rotate the ratchet ring clockwise, so that the pawls supported by the ratchet teeth on the ratchet ring snap into the installation groove on the neck of the bucket mouth, and shrink The mouth ring is locked; when taking out the neck ring, rotate the ratchet ring clockwise to make the pawl spring back and get out of the installation groove, and then the neck ring can be taken out.

When washing clothes, open the movable cover, put the clothes 43 into the washing bucket after moving the faucet to the side of the bucket, then move the water faucet to the mouth of the bucket, cover the movable cover, input the washing program data, firstly controlled by the water volume control mechanism After the water is injected to a certain amount, the electromagnetic valve is closed, and the water injection is stopped, and the program control mechanism controls the motor to start immediately, driving the hollow rotating shaft of the flange and the washing bucket to rotate, and the motor stops working until the whole washing program is finished.

In the selection of the washing program, there are two rotation modes of constant speed and angular acceleration. When rotating at a constant speed, the clothes are evenly squeezed to the wall of the bucket by the centrifugal force, and the washing liquid is driven by the rotation of the clothes, and the reaction force of the washing liquid can be changed. The clothes are flushed. During the rotation process, the washing liquid passes through the clothes and comes out of the dehydration hole due to centrifugal action, and returns to the barrel through the gap and the upper and lower return holes, and the washing liquid through the lower return hole passes through the spray limiter or sprayer. The shower sprays the clothes, which forms a cycle of centrifugal penetration washing, so that the washing effect of the clothes is better.

When it is used as angular acceleration rotation, directional rotation and bidirectional rotation can also be selected. When it is used as directional rotation, the program control mechanism controls the forward drive and reverse braking of the motor, so that the washing tub can accelerate and decelerate back and forth in a certain speed range , as the speed increases, the clothes are squeezed tightly against the wall of the bucket, and the extrusion of the centrifugal force is strengthened, and most of the washing liquid is squeezed out from the clothes; as the speed decreases, the centrifugal force on the clothes weakens and relaxes, and finally breaks away from the wall of the bucket. The washing liquid can re-immerse into the clothes, which creates a squeeze scrubbing of the clothes. When it is used as a two-way rotation, the clothes in the bucket are also turned over many times after multiple changes of direction, and can be rearranged and evenly distributed, so that the clothes can be washed more fully. Angular acceleration rotation also has the washing effect of constant rotation speed.

When the washing enters the drainage and dehydration program, in order to avoid the zero-speed start in anhydrous state and ensure the uniform distribution of clothes, the motor is driven in the direction of increasing or not decreasing the rotating speed, and the monitoring data of the rotating speed is provided by the sensor head supply.

When entering the drainage or dehydration program, the program control mechanism controls the electromagnet to turn on the power, so that the joystick is pulled down, and the dial ring on the joystick is pressed against the fork rocker arm, so that the other end of the fork rocker arm is upward. Pry, the drain valve is opened, the waste water flows into the sump through the cover of the rubber funnel, and is discharged from the outer drain hole. closure.

No matter what kind of rotation mode is selected, during the washing of clothes, the clothes rely on the buoyancy, inertia, damping effect and centrifugal force of the washing liquid to be evenly distributed, so that the washing tub can rotate smoothly.
