Fig. 2 is the cutaway view of double motor tumbling-box washing machine in accordance with a preferred embodiment of the present invention; With
Fig. 3 be Fig. 2 double motor tumbling-box washing machine simplification rearview.
The specific embodiment
In detail with reference to the preferred embodiments of the present invention, be described in the drawings its example now.In the accompanying drawings, as possible, with same or analogous Reference numeral indication similar elements.
With reference to figure 2, double motor tumbling-box washing machine in accordance with a preferred embodiment of the present invention plays the laundry motor 50 (form with motor pulley illustrates) that laundry is used when being included in operation.Stretch out from the center that utilizes the laundry pulley 52 that V-shape belt 51 is connected with the pulley of laundry motor 50 for first 70, thereby can be driven, and the central gear 72 between a plurality of planetary gears 74 is formed on first 70 front end.When center gear 72 rotated, planetary gear 74 rotated simultaneously.Central gear 72 and planetary gear 74 are placed in the internal tooth roller box 90, and internal tooth roller box 90 oneself also rotates and transmits rotatory force.Internal tooth roller box 90 is provided with a plurality of lip-deep teeth of its inner circumference that are formed on, these teeth and planetary gear 74 engagements.Internal tooth roller box 90 is cylindrical basically, and prevents that planetary gear 74 and central gear 72 from separating.
The center of all planetary gears 74 all is fixed on the rotor plate 76, thereby all planetary gears 74 rotate together relative to central gear 72, and second 80 center from rotor plate 76 stretched out and be connected with first cylinder 101.First cylinder 101 is rotated in the athletic meeting of rotor plate 76 and planetary gear 74 like this, and all planetary gears 74 rotate together, but in their direction of rotation of the relative both sides of central gear 72.
Be located at the front of laundry pulley 52 with dehydration pulley 62 that dehydration motor 60 (form with motor pulley illustrates) is connected by V-shape belt 61.The hole that axle passes through is formed on the center of dehydration pulley 62, and has formed the cylindrical the first pontes 91 consistent with the hole.A hole and the first pontes 91 that axle passes through passed in laundry first 70 of pulley 52, and bearing is installed between first 70 and the first pontes 91 rotation to help first 70.The first pontes 91 links together with internal tooth roller box 90.
Second coupling part 92 is installed in a side of internal tooth roller box 90, and this side is relative with the first pontes 91.Second coupling part 92 is cylindrical, and second 80 is passed it, and is provided with bearing to help second 80 rotation.Second coupling part 92 is connected with second tin roller 102, and the inside of second tin roller 102 is provided with first cylinder, 101, the second coupling parts 92 rotatory force is passed to second tin roller 102.
Be rotatably mounted first 70, the second 80 that explain above, the first pontes 91 and second coupling part 92.The first pontes 91 and second coupling part 92 combine with a standing part by bearing, and this standing part is connecting the bucket 2 of tumbling-box washing machine, like this by the combine rotation that help they of bearing with standing part.
With reference to figure 3, laundry pulley 52 and dehydration pulley 62 are located at the center of tumbling-box washing machine bucket 2, and laundry pulley 52 is connected with laundry motor 50 by V-shape belt 51, and dehydration pulley 62 is connected with dehydration motor 60 by another V-shape belt 61.
Laundry motor 50 and dehydration motor 60 are induction motors.Compare with the motor (BLDC motor or general-purpose type motor expensive, high power consumption) of the tumbling-box washing machine of correlation technique, because induction type motor provides uniform rotating speed and can only forward rotation and backward rotation, induction type motor has lower power consumption and more cheap.
Laundry motor 50 is preferably set to 6: 1 with the rotating ratio of laundry pulley 52.This speed reducing ratio is regulated by diameter difference or gear ratio between motor and the pulley.Simultaneously, dehydration motor 60 is preferably set to 1.4: 1 with the rotating ratio of dehydration pulley 52.
Laundry motor 50 has periodically clockwise or rotates counterclockwise the feature of first cylinder 101, therefore can use a kind of can forward and counter-rotational simple motor, dehydration motor 60 is just carried out dehydration to clothing by unidirectional high speed rotating, therefore can use a kind of correspondingly have a more motor of finite character.Like this, can use a kind of more cheap and consume electric power motor still less as dehydration motor 60 than laundry motor 50.
When operation double motor tumbling-box washing machine, laundry motor 50 periodically rotates to carry out the laundry step in forwards/reverse.When the cycle more in short-term, the operation below taking place.
When laundry pulley 52 when rotating owing to the rotation of laundry motor 50, its rotates first 70 of laundry pulley 52, in central gear 72 rotations of first 70 front end.So planetary gear 74 is owing to the rotation of central gear 72 is rotated, and reduced the rotating speed of planetary gear 74 significantly.Here central gear 72 is preferably 5.5: 1 with the rotating ratio of rotor plate 76.
Therefore, the rotation of central gear 72 passes to rotor plate 76 by one group of planetary gear 74, and the rotatory force that has reduced is rotated first cylinder 101 by second 80.
Under short situation of the cycle that forwards/reverse is rotated, when center gear 72 during in forward rotation, the internal tooth roller box 90 that is connected with dehydration pulley 62 is by the backward rotation that acts on of gear mechanism.The rotatory force of internal tooth roller box 90 is delivered to and makes first and second cylinders 101,102 rotate in opposite direction on the cylinder 102.
Such motion has just realized the effect same with the twin-roll laundering process of pulsator washing machine, and it periodically rotates in an opposite direction by a pair of cylinder and realizes, thereby can make clothing be immersed in equably in water and the washing agent.
When laundry motor 50 when the rotation period of forwards/reverse is longer, the operation below taking place.
When laundry pulley 52 began to rotate, first and second cylinders 101,102 at first rotated in an opposite direction.Through behind the preset time, first cylinder 101 is because the direction rotation that inertia force finally rotates at second tin roller 102.So just implement the laundering process of the tumbling-box washing machine of correlation technique.
Explanation now is motor operated dehydration.
Finishing laundry when beginning to dewater, at first drive laundry and dehydration motor 50,60 simultaneously at forward.Under the situation that drives two motors, initial power has obtained enhancing, thereby quickens the rotating speed of first and second cylinders 101,102 simultaneously.
Make dehydration motor 60 rotate second tin roller 102 separately if turn off laundry motor 50, because the effect of inertia force, first cylinder 101 also rotates.When the rotating speed of control first and second cylinders 101,102, suitably opening/closing dehydration motor 60 is controlled their speed.
Therefore, double motor tumbling-box washing machine according to the present invention has the advantage of following effect.
At first, induction motor is used as laundry and dehydration motor to reduce manufacturing cost.
Secondly, a pair of cylinder is done washing to realize twin-roll by motor driving separately respectively, so strengthened washing efficiency and reduced power consumption.
To those skilled in the art, clearly need not depart from the spirit and scope of the present invention and just can carry out various improvement and variation.Therefore, need only these improvement and variation in the scope of claims and their equivalent, the present invention just intention comprises them.
