BACKGROUND
Technical Field
[0001] The present invention relates to the field of washing machines, and in particular,
to a washing machine and a control method of same.
Related Art
[0002] An existing washing machine mostly uses a sealed gimbal ring, and filler therein
uses liquid or substances such as a steel ball and a steel ingot, which is filled
in a cavity of the gimbal ring. When the washing machine performs dehydration at a
high speed, according to a vibration point, the filler that can move in the cavity
of the gimbal ring will automatically slide to a position eccentrically symmetric
to the load of the washing machine, thereby reducing the overall eccentricity and
reducing the vibration noise. The eccentricity distributed during each work of the
washing machine differs, especially when loads having a large water absorption capability,
such as cotton-padded clothes, are dehydrated, the gimbal ring having fixed filler
cannot completely balance the eccentric mass. Meanwhile, when less loads or clothes
having a small water absorption capability are dehydrated, the eccentricity is small,
and the quantity of the filler in the gimbal ring will have a negative effect on the
vibration during low-speed rotation or distribution and eccentricity calculation,
which greatly affects the eccentric effect.
[0003] The existing washing machine uses the movement of the filler in the gimbal ring to
balance the eccentricity, the internal filler is sealed inside the gimbal ring, and
the internal filler is liquid or substances such as steel balls or steel ingots, so
that it is required that the leakproofness of the gimbal ring is rather high. The
service life of a washing machine is up to dozens of years, and the requirements on
the manufacturing process of the gimbal ring are high; therefore, the cost is high,
and the production efficiency is relatively low. Moreover, the weight of the gimbal
ring together with the filler therein is very large, which brings some difficulties
in assembling of the washing machine.
[0004] The patent invention with the application No.
200910158225.9 disclosed a gimbal ring device for a roller washing machine, the gimbal ring device
includes at least two annular chambers which are coaxial with a roller and disposed
at an edge of the roller, where at least one chamber is a spherical gimbal ring provided
with a ball, and at least one chamber is a liquid gimbal ring provided with a flowing
liquid; by using the two different counterweights, that is, the ball and the liquid,
at least two balance forces having different reaction speeds are generated respectively,
thereby improving the balance state of rotation of the roller of the washing machine
during dehydration. When the rotation speed is lower than a resonance point of the
roller and the outer cylinder, the liquid gimbal ring absorbs the vibration; when
the rotation speed is stabilized with the resonance point, the spherical gimbal ring
exerts the high vibration absorption performance to absorb the vibration of the outer
cylinder; for the eccentricity exceeding the total amount of the spherical gimbal
ring, the liquid gimbal ring is used to absorb the vibration. The gimbal ring device
can inhibit the vibration amplitude of the outer cylinder when it is started and it
rotates stably, thereby implementing low vibration, low noise and low cost. However,
in the above patent, once the gimbal ring is assembled to the washing machine, the
mass of the internal counterweight is determined, and cannot be adjusted according
to the load offset of the washing machine; moreover, in the working process of the
washing machine, the counterweight inside the gimbal ring also needs to be driven
to rotate, which wastes the driving energy consumption of the motor.
[0005] Therefore, the present invention is provided.

[0037] The water injection component 5 is a pipe fixedly connected to the outer cylinder
13, the bottom of the outer cylinder 13 is provided with a drainage chamber 3 that
can reserve a part of washing water, one end of the pipe is inserted into the water
input port of the gimbal ring and is not in contact with the wall of the gimbal ring,

inclined surface, a filter screen 6 is disposed at the junction, and the bottom of
the drainage chamber 3 is further provided with a water outlet 7 in communication

of the drainage chamber 3 may discharge the residual washing water when the washing
water is no longer required inside the gimbal ring after the dehydration distribution
is completed.
[0039] The outer circumference of the gimbal ring is provided with 2 to 10 water drainage
ports 8 configured to discharge the equilibrium liquid, and the water drainage port
is provided with a drainage valve 9 that can control opening and closing of the water
drainage port 8. Preferably, there are 3 water drainage ports 8 uniformly distributed

of the spring 10 in a free state is greater than the thickness of the gimbal ring,
and the length of the spring in an extreme compression state is less than the thickness
of the gimbal ring. When the washing inner cylinder 1 does not rotate, the spring
10 is in a naturally stretched state, and there is a gap between the baffle 11 and
the inner wall of the gimbal ring, that is, the drainage valve 9 is in an open state.
When the washing inner cylinder 1 rotates, because of the centrifugal force, the baffle
11 compresses the spring 10 until the baffle 11 is attached to the inner wall of the
gimbal ring, and the drainage valve 9 is in a closed state.
[0042] The drainage valve 9 may also be a solenoid valve, and the solenoid valve is electrically
connected to a control board of the washing machine, and controls open and close of
the solenoid valve through an electromagnetic signal.
[0043] A control method of a washing machine having a water input port-type gimbal ring

machine, and the washing water entering the gimbal ring through the gimbal ring water
input port 2 balances the load offset of the inner cylinder 1 during the dehydration,
and after the dehydration ends, the washing water in the gimbal ring is discharged
through the water drainage port 8.
[0045] Before the dehydration distribution, the washing water is discharged, and during
the dehydration distribution, the washing machine calculates the load offset in the
inner cylinder 1, and injects running water corresponding to the eccentricity into
the gimbal ring through the gimbal ring water input port 2, so as to balance the eccentricity
of the internal load during dehydration of the inner cylinder 1, and after the dehydration

the washing water in the gimbal ring is discharged through the water drainage port
8.
[0047] During the dehydration, the inner cylinder 1 rotates at a high speed, the centrifugal
force generated by the rotation is greater than the resistance of the spring 10, so
that the baffle 11 compresses the spring 10, and the baffle 11 closely attaches the
inner wall of the gimbal ring to enclose the water drainage port 8; when the dehydration
ends, the inner cylinder 1 gradually stops rotation, the centrifugal force gradually
reduces along with the reduction of the speed, when the centrifugal force is less
than the restoring force of the spring 10, the restoring force of the spring 10 resets

machine includes an outer cylinder 13 and an inner cylinder 1, an opening of the inner
cylinder 1 is provided with a gimbal ring, the gimbal ring is a round ring structure,

the dehydration distribution of the washing machine, a control board injects water
into the gimbal ring through the water intake structure according to the magnitude
of the load offset, so as to balance the load offset (referring to FIG. 5); and after
the dehydration ends, the drainage structure discharges water in the gimbal ring,
and during washing and rising of the washing machine, it is not required to drive
the filler in the gimbal ring to rotate, thereby reducing the mass of the inner cylinder
and reducing the drive energy consumption.

1 along an outer surface of a sidewall of the inner cylinder 1, and is in communication

shaft; the drainage structure extends from the gimbal ring at the front end opening
of the inner cylinder 1 to an inner cylinder shaft at the rear end of the inner cylinder
1 along an outer surface of a sidewall of the inner cylinder 1, and is in communication
with a drainage end of the washing machine through the internal of the inner cylinder
shaft.

of the sidewall of the inner cylinder 1 and rotates together with the inner cylinder
1, and a second rotation connector 26 that is located in the outer cylinder axle sleeve

annular sink 29 is disposed at the junction of the inner cylinder shaft 31 and the
first rotation connector 28, the first annular sink 29 and a position at the outer
surface of the inner cylinder shaft 31 is communicated through a pipe disposed inside
