Detailed Description
In order that the above objects, features and advantages of the present invention can be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.
Example one
Fig. 1 is a schematic structural view of a water suction pump connected to a drain tank, and will be further described with reference to fig. 1, 3, 4, 5, and 6.
When the washing machine starts to execute the dewatering program, the inner drum 3 of the washing machine starts to rotate slowly, the electromagnetic valve 12 communicated with the water supply tank 41 is opened, and the water suction pump 10 communicated with the water drainage tank 43 is opened.
Furthermore, because the mass distribution of the objects to be washed in the inner drum 3 of the washing machine is uneven, the inner drum 3 of the washing machine generates centrifugal force when rotating; at this time, the spring 14 connecting the washing machine drum assembly and the washing machine housing 1 is offset with the centrifugal force on the washing machine inner drum 3 by the elastic force generated by stretching or compressing, and the shaft of the washing machine inner drum 3 deviates from the position of the shaft when the shaft is static in the process of rotating due to the stretching or compressing of the spring 14.
Further, as shown in fig. 7, 8 and 9, as the inner cylinder 3 is shifted during rotation, the follower disk 5 mounted on the inner cylinder 3 and the fixed disk 4 mounted on the housing 1 through the flexible fixing member 8 are displaced relatively, so that when one or more water supply holes 51 located on the lighter side of the inner cylinder 3 are rotated, the actual rotation radius is smaller than the radius R of the circle where the water supply holes 51 are located, and the center line where the water supply groove 41 is located is R1On the annular region of (a); the water supply holes 51 are swept across the water supply groove 41 of the fixed disk 4 during the rotation, and the water supply holes 51 are swept across the opening of the water supply groove 41 once with each rotation of the inner cylinder 3, and when the water supply holes 51 are swept across the opening of the water supply groove 41, water can flow into the water supply holes 51 through the water supply groove 41; finally, water flows into the swept water supply holes 51 through the water supply groove 41 through the water pipe 13 and the electromagnetic valve 12, then flows through the pipeline 18 in the inner cylinder shaft and the pipeline 17 on the inner cylinder, and finally is injected into the corresponding balance cavity 6 through the water inlet 16 on the balance cavity 6, so that the unbalance amount of the inner cylinder 3 is reduced.
Further, as shown in fig. 7, 8 and 10, as the water continuously flows into the balancing chamber 6, the weight of which needs to be increased, the inner tub 3 of the washing machine gradually restores to dynamic balance; the rotation radius of all the water supply holes 51 is restored to a circle with a radius R, that is, all the water supply holes 51 fall into the emptying groove 42 with a center line R2Within the annulus region of (a); at this time, when the inner cylinder 3 rotates once, all the water supply holes 51 sweep the emptying groove 42 once, and the quality of water in all the balance cavities 6 cannot be changed because the drainage pump 9 communicated with the emptying groove 42 is not opened; at this time, the washing machine enters a stable dehydration state.
Further, as shown in fig. 7, 8, 9 and 11, as the dehydration proceeds, the amount of water contained in the laundry in the inner cylinder 3 decreases, the inner cylinder 3 loses the dynamic balance again, and the follower disk 5 and the fixed disk 4 are displaced again; one or more water supply holes 51 are swept through the water supply tank 41 on the lighter side of the inner barrel 3, and then water is injected into one or more balance cavities 6 on the lighter side again; at the same time, there will also be one or more feeds on the heavier side of the inner tube 3The actual rotation radius of the water hole 51 is larger than the radius R of the circle where the water supply hole 51 is located, and the center line where the water falls into the water discharge groove 43 is R3So that the water supply holes 51 sweep the water discharge groove 43 during the rotation; if water is in the balancing chamber 6 connected to the water supply holes 51, the water will be discharged to the water discharge pipe 11 through the water inlet 16 on the balancing chamber 6, the pipe 17 on the inner cylinder, the pipe 18 in the inner cylinder shaft, the water supply holes 51 and the water discharge groove 43 by the water suction pump 10 until the inner cylinder 3 reaches the balanced state again.
Further, during dehydration, if part of water leaks from a gap between the attaching surface 52 on the follower disk and the attaching surface 45 on the fixed disk in the relative rotation process of the follower disk 5 and the fixed disk 4; when the water flows outwards from the axis, the water is absorbed by the leakage-proof groove 44 and is discharged into the water discharge pipe 11 through the water discharge groove 43 and the water suction pump 10, and the pollution and damage to the inside of the washing machine caused by the leakage of the water are avoided.
Further, as shown in fig. 10, when the dehydration is about to be completed, the rotation speed of the inner drum 3 is gradually reduced, and at this time, the electromagnetic valve 12 communicating with the water supply tank 41 is closed, the water suction pump 10 communicating with the water discharge tank 43 is closed, and the water discharge pump 9 communicating with the water discharge tank 42 is opened; at this time, all the water supply holes 51 will sweep through the emptying slot 42 once with one rotation of the inner barrel 3, and when each water supply hole 51 sweeps through the emptying slot 42, the water in the balance cavity 6 communicated with the water supply hole 51 will pass through the water inlet 16 on the balance cavity 6, the pipeline 17 on the inner barrel, the pipeline 18 in the inner barrel shaft, the water supply hole 51 and the emptying slot 42 and finally be discharged to the water discharge pipe 11 by the water discharge pump 9 until all the water in the balance cavity 6 is emptied.
Further, when all the water in the balance chamber 6 is drained, the drainage pump 9 communicated with the drainage groove 42 is closed, and the dehydration process is completed.
Example two

Furthermore, because the mass distribution of the objects to be washed in the inner drum 3 of the washing machine is uneven, the inner drum 3 of the washing machine generates centrifugal force when rotating; at this time, the spring 14 connecting the washing machine drum assembly and the washing machine housing 1 is offset with the centrifugal force on the washing machine inner drum 3 by the elastic force generated by stretching or compressing, and the shaft of the washing machine inner drum 3 deviates from the position of the shaft when the shaft is static in the process of rotating due to the stretching or compressing of the spring 14.
Further, as shown in fig. 7, 8 and 9, as the inner cylinder 3 is shifted during rotation, the follower disk 5 mounted on the inner cylinder 3 and the fixed disk 4 mounted on the housing 1 through the flexible fixing member 8 are displaced relatively, so that when one or more water supply holes 51 located on the lighter side of the inner cylinder 3 are rotated, the actual rotation radius is smaller than the radius R of the circle where the water supply holes 51 are located, and the center line where the water supply groove 41 is located is R1On the annular region of (a); the water supply holes 51 are made to sweep the water supply groove 41 on the fixed disk 4 during the rotation; and the water supply holes 51 are swept once from the opening of the water supply tank 41 with each rotation of the inner cylinder 3, and when the water supply holes 51 are swept from the opening of the water supply tank 41, water can flow into the water supply holes 51 through the water supply tank 41; finally, water flows into the swept water supply holes 51 through the water supply groove 41 through the water pipe 13 and the electromagnetic valve 12, then flows through the pipeline 18 in the inner cylinder shaft and the pipeline 17 on the inner cylinder, and finally is injected into the corresponding balance cavity 6 through the water inlet 16 on the balance cavity 6, so that the unbalance amount of the inner cylinder 3 is reduced.
Further, as shown in fig. 7, 8 and 10, as the water continuously flows into the balancing chamber 6, the weight of which needs to be increased, the inner tub 3 of the washing machine gradually restores to dynamic balance; the rotation radius of all the water supply holes 51 is restored to a circle with a radius R, that is, all the water supply holes 51 fall into the emptying groove 42 with a center line R2Within the annulus region of (a); at this time, when the inner cylinder 3 rotates once, all the water supply holes 51 sweep the emptying groove 42 once, and the quality of water in all the balance cavities 6 cannot be changed because the drainage pump 9 communicated with the emptying groove 42 is not opened; at this time, the washing machine enters a stable dehydration state.
Further, as shown in fig. 7, 8, 9, and 11, as the dehydration proceeds, the amount of water contained in the laundry in the inner cylinder 3 decreases, the inner cylinder 3 loses the dynamic balance again, and the follower disk 5 and the fixed disk 4 are displaced again; one or more holes of the feed water 51 are swept through the feed water tank 41 on the lighter side of the inner cylinder 3, and then the water is injected into one or more balance cavities 6 on the lighter side again; meanwhile, one or more water supply holes 51 are arranged on the heavier side of the inner cylinder 3 to sweep the water discharge groove 43, and air is injected into the corresponding balance cavity 6 through the air pump 7, the water discharge groove 43, the water supply holes 51, the pipeline 18 in the inner cylinder shaft and the pipeline 17 on the inner cylinder through the water inlet 16; if water exists in the balance cavities 6, the injected air can discharge the water in the balance cavities 6 between the inner drum 3 and the outer drum 2 of the washing machine through the air inlets 15 on the balance cavities 6 under the action of pressure, so that the weight of the balance cavities 6 is reduced; finally, the inner cylinder 3 is in an equilibrium state again.
Further, as shown in fig. 10, when the dehydration is about to be completed, the rotation speed of the inner drum 3 is gradually reduced; at this time, the electromagnetic valve 12 communicating with the water feed tank 41 is closed, the air pump 7 communicating with the drain tank 43 is closed, and the drain pump 9 communicating with the drain tank 42 is opened; at this time, all the water supply holes 51 will sweep through the emptying slot 42 once with one rotation of the inner barrel 3, and when each water supply hole 51 sweeps through the emptying slot 42, the water in the balance cavity 6 communicated with the water supply hole 51 will pass through the water inlet 16 on the balance cavity 6, the pipeline 17 on the inner barrel, the pipeline 18 in the inner barrel shaft, the water supply hole 51 and the emptying slot 42 and finally be discharged to the water discharge pipe 11 by the water discharge pump 9 until all the water in the balance cavity 6 is emptied.
Further, when all the water in the balance chamber 6 is drained, the drainage pump 9 communicated with the drainage groove 42 is closed, and the dehydration process is completed.
