Abstract
A washing machine with a balanced system comprises a rotary drum and a control device, wherein the rotary drum is driven by a first motor to rotate, and the control device is used for controlling the first motor to run. At least three tracks are radially arranged at the bottom of the rotary drum, and at least one counter weight block is arranged on each track and can slide along the track to change the counter weight of the rotary drum, so that the rotary drum is rotatably balanced. The balanced system can change the counter weight in real time according to the balanced condition of the rotary drum, weight distribution of the rotary drum is flexibly corrected, so that the rotary drum is more stable in the high-speed spin-drying process, and noise is reduced.
Description
[technical field]
The present invention relates to a kind of washing machine, relate in particular to the washing machine with the cylinder automatic-balancing system.
[background technology]
Washing machine comprises a steel ladle that hangs in casing usually, and a rotatable cylinder is equipped with in steel ladle inside.In the process that clothing is dewatered, the cylinder High Rotation Speed.At this moment, due to the clothing skewness, the centrifugal force of cylinder is uneven, will cause cylinder acutely to rock together with steel ladle, affects the service life of dehydrating effect and washing machine, can produce very large noise simultaneously, washing machine integral body is produced mobile on supporting surface.The above-mentioned impact that produces in order to reduce the clothing skewness, balance weight is assembled in suitable position outside steel ladle usually.Because balance weight is not directly to be loaded on cylinder, the centrifugal force inequality of cylinder still exists, thereby can produce very large noise.And the position of balance weight is fixed, and can not fundamentally solve the problem of centrifugal force inequality.In addition, balance weight is often very heavy, affects the carrying of washing machine, and the occupied a large amount of volumes of balance weight also hinder the further densification of washing machine.
[summary of the invention]
One of purpose of the present invention is to provide a kind of washing machine that overcomes the prior art above shortcomings.
For above purpose, the technical solution used in the present invention is: a kind of washing machine with balance sysmte, comprise the cylinder by the first motor-driven rotation, control the control device of the first motor rotation, cylinder bottom is provided with at least three tracks along radial direction, thereby has at least one can slide to change the balancing weight that the cylinder counterweight realizes the drum rotating balance along track on every track.
One of improvement the most of the present invention, control device is connected with viberation detector, and controls the movement of balancing weight according to the testing result of viberation detector.
as one of improvement of the present invention, control device is configured to balancing weight is carried out following control: when the vibration amplitude that detects when viberation detector surpasses particular value, control device makes the first balancing weight move one section unit distance, if the vibration amplitude that this moment, viberation detector detected reduces, continue to move the first balancing weight along equidirectional, until the vibration amplitude that viberation detector detects reaches allowed band, if the vibration amplitude that this moment, viberation detector detected increases, control device makes the second balancing weight move one section unit distance, viberation detector detects vibration amplitude simultaneously, control device determines that according to the testing result of viberation detector the second balancing weight continues mobile or another balancing weight is moved.
As one of improvement of the present invention, every track is provided with a leading screw, respectively by second a motor-driven rotation, described balancing weight is sheathed on leading screw and is driven it by rotatablely moving of leading screw along the track linear slide, and described control device is controlled the running of the second motor according to the testing result of viberation detector.
As one of improvement of the present invention, described the second motor and control device wireless connections.
As one of improvement of the present invention, at least three tracks are structure as a whole.
As one of improvement of the present invention, at least three tracks are connected in cylinder bottom, and are fixedly connected with the driving shaft that drives drum rotating in the center that track converges.Cylinder is provided with the outer barrel of holding cleaning solution outward, and the auxiliary balance piece is housed on described outer barrel.
As improvement of the present invention it, the auxiliary balance piece is near the front end setting of outer barrel.
The balance sysmte that washing machine of the present invention comprises can be revised the distribution of weight that cylinder carries neatly according to the equilibrium condition real time altering counterweight of cylinder, thereby makes cylinder more stable in high speed drying process, has also reduced noise.In addition, the balance sysmte that provides in the present invention occupies less space with respect to prior art, thereby can make washing machine compacter.
[description of drawings]
Fig. 1 is the washing machine organigram;
Fig. 2 is washing machine drum balance sysmte and control circuit schematic representation thereof.
[specific embodiment]
As shown in Figure 1, washing machine 1 has outer barrel 3 that 2, one of casings hold cleaning solution by hanging spring 4 and damper 5 is suspended in casing 2.Cylinder 6 is positioned at outer barrel 3 and rotatable by the first motor 8 drivings.
Motor 8 is fixedly installed on outer barrel 3 by the mounting bracket 9 that is attached thereto.Belt wheel 10 is fixedly connected with by the center of driving shaft 11 with rolling stand 12, rolling stand 12 and then be fixedly connected with the bottom of cylinder 6, and belt wheel 10 is in transmission connection by belt 14 with machine shaft 13 simultaneously.So the first motor 8 can drive cylinder 6 rotations.Washing machine 1 also comprises control device 15, and it controls the running of the first motor 8 according to programming.
In order to detect and the vibrations of index drum 6 and outer barrel 3, be provided with the viberation detector 16 that detects cylinder 6 and outer barrel 3 vibration amplitude in washing machine 1, also be provided with balance sysmte to regulate the vibrations of cylinder 6.Wherein, the balance sysmte auxiliary balance piece 18 that comprises the automatic balancing arrangement 17 that is loaded on cylinder 6 bottoms and arrange near the front end of outer barrel.
As shown in Figure 2, automatic balancing arrangement 17 comprises the rolling stand 12 that is fixedly connected with the bottom of cylinder 6.Rolling stand 12 comprises the arms 19 three integrative-structures and equiblibrium mass distribution along the radius roller direction, and every arm 19 is provided with a track 20, and every track 20 is provided with a leading screw 21, can drive rotation by second motor 22 respectively.Balancing weight 23a, a 23b, 23c are housed on every leading screw 21.When leading screw 21 rotated under the second motor 22 drives, balancing weight 23a, 23b, 23c can slide along track 20 separately.
Because cylinder 6 is rotatable, preferably, the second motor 22 and control device 15 wireless connections, controlled device 15 controlled in wireless.In the present embodiment, the physical circuit connected mode shows as: control device 15 is connected with a sender unit 24, and the second unit 22 is connected with signal receiving device 25 respectively.The signal that control device 15 sends is received by signal receiving device 25 after sending by sender unit 24, and signal receiving device 25 is according to the unlatching of each second motor 22 of the signal controlling of receiving or close.
