The specific embodiment

The invention provides a kind of suspension type dual-impeller washing machine outer-tub hanging device.

The outer wall of general swirl washing machine external barrel is uniformly distributed with four erectings by overhang along the circumference, the link position of four erectings by overhang and outer bucket is to be positioned at outer barrel bottom. as shown in Figure 1, be that impetus is positioned at outer barrel bottom. pettyly to be arranged at outer barrel bottom for assorted, rather than outside the bucket suitable for reading? long-pending design experiences and the theory analysis of being engaged in washing machine for a long time of the present inventor, think that this is owing to be provided with drive motors below the outer barrel bottom of rotary drum washing machine, decelerator, interior bucket is housed in the outer bucket, washings and washing clothes, in washing process, the rotation that is produced, swing mainly is in the bottom, the effect of four suspension rods is not only and is born weight, but also to help reducing outer bucket swing, therefore, have only four suspension rods to be hung on the swing that outer barrel bottom just can help reducing outer bucket, further as can be known from the result of mechanical analysis, should be to be positioned at the rotation height of C.G. position that horizontally rotates object. hang or the Support Position far away more from the rotation center of gravity of rotating object, then the rotary oscillation of rotating object is big more.

See U.S. Pat 6,220 again, 063 disclosed suspension double-agitator washing machine, its outer bucket 1 is arranged on the boatswain chair 5, and four suspension rods 4 of these boatswain chair 5 usefulness are hung in the casing.Drive motors be fixedly arranged on boatswain chair 5 below, and coaxial with outer bucket.The position of this boatswain chair is between the interior bucket of rotation cleaning solution, rotation and impeller that is arranged in electric rotating machine and the outer bucket, roughly also is the rotation height of C.G. position that horizontally rotates object.

According to this analysis, the present inventor especially clearly proposes in the design of suspension double-agitator washing machine: hanging of erecting by overhang highly is the height of the rotation center of gravity that horizontally rotates thing of bucket outside connecting.Referring to Fig. 3, the outer bucket of described connection horizontally rotate thing, comprise: interior bucket 11 and impeller 12 and the washing clothes and the washings of drive motors 9, the clutch rotating shaft 10 that connects drive motors 9, connection rotating shaft 10, the height of described rotation center of gravity are positioned at 20 barrels of bottoms of outer bucket on the upper side.The height of described rotation center of gravity is 1/10～2/10 of an outer logical height, and the best is 1.8/10.

In the specific embodiment shown in Fig. 3,4,5, a kind of suspension type dual-impeller washing machine outer-tub hanging device provided by the present invention, be arranged at outer bucket 20 bottoms, described outer bucket 20 comprises top cylinder 21 and the billiard table shape bottom 22 that is connected described cylinder 21, described outer bucket erecting by overhang is made up of two suspension rod mount pads 30, two strut mount pads 31, two support bars 36 and two suspension rods 37, wherein:

Described suspension rod mount pad 30 and strut mount pad 31 have L shaped plate 32, be provided with in the both sides of L shaped plate 32 and connect bottom the described outer bucket billiard table shape 22 floor 33, make L shaped plate 32 be in horizontal and vertical position, horizontal component in described L shaped plate 32 is provided with suspension rod installing hole 34 and strut installing hole 35, and described suspension rod installing hole 34 and strut installing hole 35 are on 20 barrels of bottom same level heights on the upper side of outer bucket; Described two support bars 36, the hinged connection strut of one end installing hole 35, the hinged connection washing machine pedestal of the other end; Described two suspension rods 37, the hinged connection suspension rod of one end installing hole 34, bight, back, the other end hinged connection casing of washing machine upper end.The angle of described support bar and suspension rod projection in the horizontal direction is 90 °, promptly along the even radial distribution of outer bucket circumference, makes four bars stressed evenly.The included angle A of described support bar and outer bucket central axis is between 0～5 °, is preferably 0～3 °, and the best is 1.5 °.The included angle B of described suspension rod and outer bucket central axis is between 0～10 °, is preferably 0～3 °, and the best is 1.5 °.Big more with the angle of central axis, the component of then resisting horizontal hunting is big more, but angle is big more, then requires casing also big more, through overtesting, selects above-mentioned angle numerical value to be advisable.

For making damping effect better, described support bar 36 and suspension rod 37 are selected the damping bar for use.

For in use, detect outer bucket swing situation in real time, be provided with amplitude sensor 38 between bucket sidewall and the casing of washing machine outside.Washing machine controller will in time be adjusted the motor rotary speed of washing and dehydration according to the amplitude sensor 38 real-time results that detect, and bucket remains in the hunting range that is allowed outside making.Used amplitude sensor is the electromagnetism force cell.

The installation site of two support bars and two suspension rods is to make the center plane of symmetry of two support bars or two suspension rods consistent with the center plane of symmetry of two impellers.Four suspension rods that replace prior art with two support bars, two suspension rods, be since suspension double-agitator washing machine in the course of the work, the bucket dehydration is around the rotation of vertical axis in not only having, and also having impeller and impeller to drive the rotation of washing clothes around trunnion axis, two support bars and two hanging rod structures help the vibrations that rotation produced of opposing connection trunnion axis and the counteracting of impact.
