Thereby, make discoid impeller structure's whole thickness, reduce the setting from the periphery to the inner periphery, make impeller structure's rotatory focus more be close to the middle part, and then can effectively prevent the eccentric effect of impeller rotation in-process.

Example two

The embodiment introduces an impeller structure, and the impeller structure is based on the first embodiment and further has the following distinguishing technical characteristics:

as shown in fig. 1 to 8, in this embodiment, a sealed annular chamber 3 is disposed inside the impeller structure, and the annular chamber 3 is filled with a balancing liquid. Through set up the sealed annular chamber who is filled with balanced liquid in impeller structure inside, make the rotatory in-process balanced liquid of impeller receive centrifugal force effect and outside peripheral direction to correspond the adjustment, make the rotatory focus of impeller more be close to the center setting to the focus of impeller structure, and then can effectively reduce the eccentric displacement of the rotatory in-process of impeller. Meanwhile, after the impeller is arranged on the drum of the washing machine, when the washing machine is dehydrated and the drum rotates at a high speed, the impeller adjusts the gravity center of the drum correspondingly, so that the drum is leveled, and the vibration and noise of the drum during the operation of the washing machine are effectively reduced.

In this embodiment, the impeller structure is disc-shaped, a circle of annular chamber 3 is arranged at the periphery of the disc-shaped impeller structure, and the annular chamber 3 is filled with the balance liquid. By providing the annular chamber 3 filled with the balancing liquid at the outer periphery of the pulsator structure so that the balancing liquid is at the outermost periphery of the pulsator, the leveling effect of the balancing liquid is maximized.

In this embodiment, a plurality of spaced radially extending ribs 14 are provided in the annular chamber 3, and are used to divide the annular chamber 3 into a plurality of independent adjusting chambers 31, and each adjusting chamber 31 is filled with a balance liquid. Through separating annular chamber 3 for a plurality of independent cavities to when making balanced liquid along with the impeller rotation, usable recoil power effect that receives the cavity separation carries out instantaneous regulation to vibrations, the counter rotation of impeller, makes the impeller operation more steady.

In this embodiment, each of the ribs 14 is provided with a notch, and the adjacent adjustment chambers 31 are communicated with each other through the notch 15 on the corresponding rib 14, so as to flow the balance liquid between the adjacent adjustment chambers 31. Through setting up the opening, make the balanced liquid of each independent regulating chamber can exchange the flow each other to the liquid level height of the balanced liquid in each regulating chamber keeps the same, and then effectively guarantees that the focus of impeller structure is in center department.

In this embodiment, the blocking rib is provided with a first gap 151 near the inner periphery of the annular chamber 3 and a second gap 152 near the outer periphery of the annular chamber 3. Through set up the second opening in the periphery of annular chamber, make balanced liquid can flow in the laminating chamber periphery wall when the impeller structure is rotatory to maintain impeller structure balance. Meanwhile, the second gap is smaller and cannot allow a large amount of balance liquid to flow instantaneously, and the inertia of the balance liquid can be used for leveling the impeller when the impeller rotates in a reversing mode and at an equal node. And when the impeller structure is static and does not rotate, the balancing liquid can flow among the chambers through the first openings so as to level the static impeller.

Preferably, the first gap 151 and the second gap 152 are located at the bottom of the rib 14 and the joint with the bottom wall of the annular chamber 3, so as to ensure that the balancing liquid in the annular chamber 3 can pass through the rib and exchange flow between adjacent chambers.

In this embodiment, the outer peripheral portion of the annular chamber 3 is higher than the inner peripheral portion of the annular chamber 3, so that after the rotation of the pulsator stops, the balancing liquid in the annular chamber 3 can flow toward the center of the pulsator in a converging manner, and the balancing liquid flows toward the outer peripheral portion under the action of centrifugal force when the pulsator rotates, thereby optimizing the leveling effect of the pulsator structure.

In this embodiment, the blocking rib 14 for partitioning the annular chamber 3 is formed by the radial support rib 11 provided on the pulsator body 1, so that the annular chamber 3 is partitioned into a plurality of independent chamber structures 31.

In this embodiment, the supporting member 2 is annular, the outer periphery of the annular supporting member 2 is correspondingly attached to and hermetically connected with the outer periphery of the pulsator main body 1, a circle of second annular supporting ribs 122 protruding downward is arranged on the pulsator main body, the second annular supporting ribs 122 are correspondingly attached to and hermetically connected with the inner periphery of the annular supporting member 2, and the pulsator main body on the outer peripheral side of the second annular supporting ribs 122 and the supporting member 2 enclose the annular chamber 3 together; preferably, as shown in fig. 5, the second annular rib 122 is provided with a liquid injection port 32 communicated with the annular chamber 3 for injecting the balancing liquid into the annular chamber 3.

In this embodiment, as shown in fig. 2, 3, 7 and 8, the support member 2 is provided with a liquid outlet 33 communicated with the annular chamber 3 for flowing out the equilibrium liquid in the annular chamber 3; preferably, the outlet opening communicates with the lowermost part of the annular chamber 3. Meanwhile, in order to ensure that the balance liquid does not flow out in the rotation process of the impeller, a detachable plug is respectively installed at the liquid injection port 32 and the liquid outlet port 33. Of course, any one of the liquid injection port 32 and the liquid outlet port 33 may be provided on the pulsator structure, so that the pulsator structure can simultaneously integrate the dual functions of injecting the balance liquid into the chamber and flowing the balance liquid out of the chamber.

In this embodiment, the equilibrium liquid injected into the annular chamber 3 of the pulsator structure needs to satisfy the following conditions: the total amount of injected balancing liquid is more than one half of the volume of the annular chamber 3 and less than nine tenth of the volume of the annular chamber 3. Therefore, the balancing liquid injected into the cavity can smoothly flow, and the balance of the impeller is effectively adjusted.
