Description
Technical field
The present invention relates to household appliance technical field, especially relate to a kind of pulsator washing machine.
Background technology
Washing machine can be divided into stirring-type, drum-type and impeller-type three types usually.
The inner core central authorities of agitator type washing machine are provided with a stirring rod and several agitators, stirring rod and agitator can according to different clothing quality, degree of fouling, washings quality etc. or rotate back and forth soon or slowly within the scope of 360 °, and clothing is pulled rub back and forth in bosom, realize removing spot.Agitator type washing machine has outstanding clean ability, but in washing process, sound is comparatively large, can produce excessive rocking, and wear of clothes is also more serious.
Tumbling-box washing machine has the cylinder that the horizontal or tilting inner surface of level is provided with the rolling rib of multiple projection usually.During washing, water, washing agent and clothing are loaded in cylinder, and cylinder slowly runs under the drive of motor.Clothing is constantly promoted and is thrown in cylinder, then promotes and throw, does repeating motion.Just in this repeating motion process, clothing under the acting in conjunction of washing powder and water by washes clean.Tumbling-box washing machine have not damaging laundry, water loss few, washed the advantages such as rear clothing can not be wound.But on the other hand, tumbling-box washing machine has the noise be harmful to health, and consumes power is many, and be that fully clean its required time of clothing is relatively long.
Pulsator washing machine utilizes the frictional force produced between the current of motion and clothing to carry out washing clothes, and wherein, the motion of water is generally rotate generation by a discoidal impeller with positive and negative direction.Pulsator washing machine has outstanding clean ability, and required wash time is shorter.In addition, pulsator washing machine also have noise low, shake the advantages such as little, price is more cheap.
Fig. 1 shows a kind of partial sectional view of existing pulsator washing machine.See Fig. 1, be provided with one and in this urceolus, be provided with an inner core 2 rotationally for holding the cylindrical outer barrel (not shown) of water in casing 1, the sidewall of inner core 2 is provided with multiple hole 2a that water can be made to flow between inside and outside cylinder.An impeller 3 is arranged on the inside bottom of inner core 2, and this impeller 3 is connected with a driving shaft (not shown), and this driving shaft is driven by a motor (not shown).The upper surface of impeller 3 is provided with the washing rib 3a of multiple upwards projection radially from center.During work, the forward and reverse rotation of impeller, washings form the current of rotation under washing rib 3a stirs, and rub, thus reach the object of washing clothes between this current and clothing.The top of casing 1 is also provided with a top cover 4 and a case 5, and case 5 is used to open or close the opening that can be seen washing machine internal.In addition, the sidewall of inner core 2 is also provided with usually the filter screen 6 for filtering the flock formed in laundry processes.
Because pulsator washing machine relies on current to wash, therefore, current are most important to clean ability, and current stir generation by the impeller rotated, and limit by impeller shape and rotation mode thereof.
Existing impeller, see Fig. 2, Fig. 3, Fig. 4, comprises a circular impeller dish 1, and the upper surface of impeller dish 1 is provided with the washing rib 3 of upwards the middle part boss 2 of projection and several upwards projections, and washing rib 3 hoop is evenly distributed on around the boss 2 of middle part.The lower surface of impeller dish 1 is provided with multiple ring stiffener 4 and polylith impeller blade 5, and each impeller blade 5 is connected with the ring stiffener 4 of outermost, is provided with dowel (sign) between ring stiffener 4.Radius is minimum, be positioned at the ring stiffener 4 of inner side is provided with pulsator lining 7 for being connected with driving shaft of washing machine.The impeller blade 5 of existing impeller is all radially distribute straight in the middle part of impeller, and and horizontal plane.During laundry, impeller blade 5 is to surrounding exclusion washings, washings below impeller are moved upward through the flow-guiding channel be arranged on inside inner core, and spray to bottom inner core from the opening part of top, and the place such as the through hole 6 of portion of washing water on impeller dish 1 above impeller and the gap between impeller dish 1 periphery and inner core flows into below impeller, thus form one-way circulation current in vertical guide.No matter impeller is forward or rotates backward, and in this vertical guide, the direction of one-way circulation current can not change.These one-way circulation current are unfavorable for that solving clothing is wound around problem, and once clothing is wound around, not only clothing is difficult to by wash clean, and the heavy burden of whole washing machine can be serious eccentric, and mechanical loss increases greatly, and vibration and noise also increase thereupon; This adverse effect is especially obvious in the water smoking of automatic washing machine.
Thus, how to design a kind of rotary drum washing machine, its can produce the current of specific modality with impeller, effectively can reduce clothing and be wound around, be have technical problem to be solved.
